Abstract:
In this study, HP/ENR blends were prepared in aqueous solution with different hydrophilic polymers for rubber glove donning coating application. HP/ENR blend films were prepared using cast films technique to investigate the film formation prior to coating onto rubber glove. The films surface morphology were characterised using Scanning Electron Microscopy (SEM) and Light Microscopy (LM). While, the thermal properties of the films were determined using Differential Scanning Calorimetry (DSC). The microscopy results showed that coherence film formation can be obtained even though the PVA/ENR and PAA/ENR blends were immiscible. DSC result showed that the glass transition temperature (Tg) of the blends shifted to higher temperature compared with Tgof ENR. The preliminary evaluation of coating onto rubber latex film indicated that PVP/ENR blend is feasible as coating material.

Abstract:
Chitosan and chitosan-nanoparticles were combined to prepare biobased and unplasticized film blends displaying antimicrobial activity. Nanosized chitosans obtained by sonication for 5, 15, or 30 min were combined with chitosan at 3:7, 1:1, and 7:3 ratios, in order to adjust blend film mechanical properties and permeability. The incorporation of nanosized chitosans led to improvements in the interfacial interaction with chitosan microfibers, positively affecting film mechanical strength and stiffness, evidenced by scanning electron microscopy. Nanosized or blend chitosan film sensitivity to moisture was significantly decreased with the drop in biocomposite molecular masses, evidenced by increased water solubility and decreased water vapor permeability. Nanosized and chitosan interactions gave rise to light biobased films presenting discrete opacity and color changes, since red-green and yellow-blue colorations were affected. All chitosan blend films exhibited antimicrobial activity against both Gram-positive and Gram-negative bacteria. The performance of green unplasticized chitosan blend films displaying diverse morphologies has, thus, been proven as a potential step towards the design of nontoxic food packaging biobased films, protecting against spoilage microorganisms, while also minimizing environmental impacts.

Abstract:
Silk fibroin (SF)/alginate blend films have been prepared for controlled release of tetracycline hydrochloride, an antimicrobial model drug. The blend films were analysed by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and UV-vis spectroscopy. The functional groups of the SF/alginate blends were monitored from their FTIR spectra. The homogeneity of the blend films was observed from SEM images. The dissolution and film transparency of the blend films depended on the SF/alginate blend ratio. Thein vitrodrug release profile of the blend films was determined by plotting the cumulative drug release versus time. It was found that the drug release significantly decreased as the SF/alginate blend ratio increased. The results demonstrated that the SF/alginate blend films should be a useful controlled-release delivery system for water-soluble drugs.

Abstract:
To improve the properties of silk fibroin film, the silk fibroin/pyrrolidone blend films were prepared by mixing silk fibroin and pyrrolidone solution at different ratios. The structure and mechanical properties of blend films were characterized. X-ray diffraction was used to investigate structure of the SF/PYR films, and the results indicated that the blend films were composed of the β-sheet form. Tensile strength and elongation at break of blend films were measured using an instron tensile tester. The results showed that tensile strength and elongation at break of blend films were high enough for application. Furthermore, the films’ flexibility was significantly improved. The optical clarity of blend film was tested by Microplate system. It can be seen from the results that optical clarity is not stable, but in some particular ratios we also can get high light transmittance blend films. At last, biocompatibility of blend films (the rate of the blend film is 30%) was accessed with L929 cell. The results showed that all types of blend films were able to support cell adhesion and proliferation. In addition, the cellular morphology of the cells cultured on blend films was better than that on silk fibroin films. In view of the mechanical properties and optical clarity, combined with their ability to support L929 proliferation suggests that this blend films will offer new options in many different biomedical applications.

Abstract:
This paper described the tensile, thermal, and moisture absorption characteristic of polyvinyl alcohol (PVA) / bengkuang (Pachyrhizuserosus) starch blend films. The film was produced through the solution casting method. Tensile, thermogravimetric analysis and moisture test were studied to determine the tensile strength, thermal stability, and moisture absorption, respectively. The highest tensile strength (TS) was 15.86 ± 0.69 MPa for pure PVA film. This result was higher than bengkuang starch and its blends film. Tensile elongation (TE) decreased as increased bengkuang starch content in PVA. The thermal degradation of PVA film was higher 10°C than bengkuang starch films in range temperature 200-380°C. The addition of bengkuang starch in PVA also increased moisture absorption. The highest moisture absorption was in the bengkuang starch film. This blend film’s tensile, thermal, and moisture properties probably suggested it could be suitable for food packaging.

Abstract:
PEG (Polyethylene glycol) of biodegradable polymer materials were used to prepare (1 wt%, 3 wt%, 5 wt% and 7 wt%) PEG films. Polyvinyl alcohol (PVA) was added to the PEG solution and mixed films with different mass fraction ratios of PEG/PVA (2:0.66, 2:2 and 2:6) were produced. Sericin (SS) was added to the PEG/PVA mixed solution to make PEG/PVA/SS mixed films with different mass fraction ratios (2:1:2, 1:5:2, 1:5:1, 2:5:1 and 1:1:1). The scanning electron microscope, film thickness measurement, tensile test and the swelling degree and dissolution loss rate test were used to analyze the mixed film. The research results showed that under the experimental conditions the PEG blend film had good film forming properties. The thickness of the blend film increased with the increase of solute mass fraction. The break strength of the PEG/PVA blend film increased with the increase of PVA mass fraction. The break strength, break stretch and break elongation of the PEG/PVA/SS blend film were all good and increased with the increase of PVA content. The results of swelling degree and dissolution loss rate showed that both PEG/PVA and PEG/PVA/SS blend films had good water-holding properties. The dissolution loss rate of blended films was less than 50% besides PEG/PVA (2:2) and PEG/PVA/SS (1:1:1) blend film.

Abstract:
Impedance-type humidity sensors based on EuCl2, Eu2O3 and EuCl2/Eu2O3 blend films were fabricated. The electrical properties of the pure EuCl2 and Eu2O3 films and EuCl2/Eu2O3 blend film that was blended with different amounts of EuCl2 were investigated as functions of relative humidity. The influences of the EuCl2 to the humidity-sensing properties (sensitivity and linearity) of the EuCl2/Eu2O3 blend film were thus elucidated. The impedance-type humidity sensor that was made of a 7 wt% EuCl2/Eu2O3 blend film exhibited the highest sensitivity, best linearity, a small hysteresis, a fast response time, a small temperature coefficient and long-term stability. The complex impedance plots were used to elucidate the role of ions in the humidity-sensing behavior of the EuCl2/Eu2O3 blend film.

Abstract:
Organic semiconductors display a wide array of enticing properties for the fabrication of novel electronic devices. Mechanical flexibility provides the potential for robust, conformable devices; while wide-area and low-temperature deposition enables the manufacture of low-cost, disposable electronics. This means that the commercial applications should be wide-ranging, as long as the performance and stability of devices based on organic semiconductors are sufficient. One of the most promising organic thin-film transistor (OTFT) systems that have been demonstrated in recent years involves the blending of small molecule and polymer organic semiconductors. A blend of the high hole mobility small molecule 2,8-difluoro 5,11 triethylsilylethynyl anthradithiophene (diF-TES ADT) with the amorphous semiconducting polymer poly(triarylamine) (PTAA) is investigated in this thesis. This blend system has been shown to allow considerable control over processing from solution and charge carrier mobilities of up to 3 cm^2/Vs. The aim of this thesis is to provide a deeper understanding of the critical charge transport and stability characteristics of this blend system, while also investigating the system's suitability to a high-throughput spray-deposition technique. In the first part of this thesis the fundamental charge transport characteristics of the diF-TES ADT:PTAA blend system are investigated. The densities of band-gap tail states in blend films of differing composition are found to be exhibit considerable thermal broadening at low temperatures, and at high temperatures are controlled by the concentration of the small molecule component in the blend. In the second part of the work the electrical and environmental stability of blend OTFTs is studied. The devices exhibit state-of-the-art bias stability in an inert environment, however exposure to air and elevated temperatures highlights some interesting degradation pathways which are investigated. Finally, the blend system was used with a high-throughput spray deposition technique. Subsequent spray deposition of semiconductor and ultra-thin dielectric layers was demonstrated, resulting in the fabrication of low-power OTFTs operating at -4 V and exhibiting hole mobilities on the order of 1 cm^2/Vs.

Abstract:
Sunlight is sustainable, clean and readily available energy source, which is one of the potential alternatives to the traditional energy sources. Recently, the organic photovoltaics (OPVs), in particular polymer solar cells (PSCs), have attracted increasing attention owing to their outstanding properties such as low cost, lightweight, flexible, allowing vacuum-free fabrication process and thin-film architecture. These advantageous material and manufacturing features of PSCs provide the opportunities for many novel applications. However, the lower power conversion efficiencies (PCEs) of PSCs compared to inorganic solar cells hinder their competition in the marketplace. This thesis covers the basic principles of the PSC, strategies for enhancing PCEs as well as the recent development of PSCs. The importance of the source materials has been also demonstrated and discussed. Due to a large number of possibilities, limited resources and time, it is not feasible to do all the work experimentally. Therefore, for continuing advance development of PSCs, the device performance should be modeled as a function of material parameters, which requires the knowledge of material properties, in particular the complex index of refraction N= n - ik. Accurate determination of the optical functions of the active layers and light trapping layers commonly used in PSCs by using the spectroscopic ellipsometry (SE) has been demonstrated. In order to acquire reliable solutions, the methodology including multiple sample analysis, combinations of different measurement techniques, selection of models, the rigorous fitting procedures and the independent verification have been proposed. The obtained information can be used in the simulation to optimize device architectures, model device performance as well as characterize novel materials.

Abstract:
In the first part of this two part thesis, interaction parameters of nitrocellulose with various solvent systems were investigated by Inverse Gas Chromatography. From these data, the solubility parameters of nitrocellulose were determined at a series of nitration levels which were used to guide the selection of suitable plasticizers for nitrocellulose films. Subsequent dynamic mechanical experiments were then used to evaluate the effectiveness of the blend formulations in broadening the glass transition dispersion of the nitrocellulose blended films; in addition, stress-strain experiments were done in order to evaluate the tensile modulus of the nitrocellulose blends. In the second part of this thesis, both dynamic mechanical thermal analysis and dielectric thermal analysis were used to evaluate the relaxation properties of thin film polysulfone coatings and the effect of substrate surface topography on these properties. Both dynamic mechanical and dielectric thermal analysis revealed that the topographical nature of the substrate influenced the linear viscoelastic properties of the thin film coatings and that the extent of this influence was dependent on the coating thickness.

Abstract:
Samuel Beckett penned novels, short stories, poetry, stage plays, radio plays, and scripts—and he did each in a way that blended genre, challenged the norms of creative writing, and surprised audiences around the globe. His experimental approach to creative writing included the use of absurdism, genre-hybridization, and ergodicism, which led to Beckett fundamentally changing the approach to creative writing. His aesthetics have trickled down through the years and can be seen in contemporary works, including Aimee Bender’s short story collection The Girl in the Flammable Skirt and Mark Z. Danielewski’s novel House of Leaves[1]. By examining these works in comparison to Beckett, this project hopes to illuminate the effects of Beckett’s experimentation in form and genre on contemporary creative writing. [1] The word ‘house’ appears in blue to honor Danielewski’s decision to have the word printed in that color each time it appears in his novel.

Abstract:
L'attuale tendenza nel confezionamento degli alimenti è orientata alla sostituzione di polimeri non biodegradabili a base di petrolio con materiali di imballaggio ecologici e che possano prolungare anche la shelf-life degli alimenti. In questo contesto, il progetto Ph.D. ha preso in considerazione lo sviluppo di film misti a base di chitosano arricchiti con composti antimicrobici naturali (oli essenziali) e di sintesi (etil lauroil arginato) per applicazioni di confezionamento alimentare sostenibile. L'intero progetto è stato diviso in cinque parti principali. Il capitolo I presenta una breve introduzione sui recenti progressi dei film costituiti da miscele a base di chitosano. Il motivo per cui è stato scelto il chitosano come biopolimero principale in questo studio e nella revisione della letteratura riguardante la miscelazione del chitosano con altri biopolimeri è stata descritta. Nel capitolo II, i film attivi a base biologica e doppio strato sono sviluppati mediante tecnica solvent casting, usando chitosano e gelatina come biopolimeri, glicerolo come plastificante e etil lauroil arginato (LAE) come composto antimicrobico. I risultati hanno mostrato che i film di miscelazione presentavano una resistenza alla trazione e un modulo elastici più elevati e una permeabilità al vapore acqueo inferiore rispetto ai film a doppio strato (p <0,05). I film bilayer hanno dimostrato un’efficace barriera contro la luce UV e valori di trasparenza inferiori (p <0,05). Gli spettri FT-IR hanno indicato la presenza di interazioni tra chitosano e gelatina, in particolare interazioni elettrostatiche e formazione di legami idrogeno. Tuttavia, l'aggiunta di LAE non ha interferito nella struttura della rete. I film attivi contenenti LAE (0,1%, v / v) hanno inibito la crescita di quattro patogeni alimentari tra cui Listeria monocytogenes, Escherichia coli, Salmonella typhimurium e Campylobacter jejuni. Nel capitolo III, sono sviluppati film a base di miscela chitosano-gelatina arricchita con cannella, citronella, chiodi di garofano rosa, noce moscata e oli essenziali di timo (1%, v / v) e le loro proprietà fisiche, ottiche, meccaniche, di barriera all'acqua e microstrutturali sono state valutate per applicazioni di confezionamento alimentare attivo. I risultati hanno confermato le interazioni intermolecolari tra i gruppi funzionali degli oli essenziali con i gruppi idrossile e amminico della rete di film di chitosano-gelatina. L'incorporazione di diversi oli essenziali ha migliorato notevolmente le proprietà di barriera UV. I film sviluppati, con particolare riguardo a quelli integrati con l'olio essenziale di timo, erano efficaci contro i quattro comuni patogeni alimentari testati. Il capitolo IV si concentra sullo sviluppo di film attivi basati sulla miscelazione di biopolimeri naturali (chitosano) e sintetici (polivinilico alcool). Sono stati sviluppati film in miscela di chitosano, polivinil alcool e LAE, incorporato in questi film a diverse concentrazioni (1-10%, p / p). I risultati hanno mostrato che alti livelli di LAE hanno influenzato negativamente sulle proprietà di barriera meccanica e permeabilità all'acqua. Anche in questo caso film attivi sviluppati erano efficaci contro quattro agenti patogeni alimentari testati. Il capitolo V rappresenta la conclusione di questa tesi, e presenta una sintesi dei punti salienti dei risultati importanti, ottenuti in questo studio.
The current trend in food packaging is oriented towards the substitution of non-biodegradable petroleum-based polymers by packaging materials that are eco-friendly and can prolong the food shelf life as well. In this context, this Ph.D. project aims to the development of chitosan-based blend films enriched with natural (essential oils) and synthetic (ethyl lauroyl arginate) antimicrobial compounds for sustainable food packaging applications. The overall project has been divided into five main parts. The brief description of each chapter is presented here: Chapter I presents a brief introduction to the recent advances of chitosan-based blend films for food packaging applications. The reason for selecting chitosan as the main biopolymer in this study and literature review concerning blending chitosan with other biopolymers has been described. Chapter II aims to develop blend and bilayer bio-based active films by solvent casting technique, using chitosan and gelatin as biopolymers, glycerol as a plasticizer and ethyl lauroyl arginate (LAE) as an antimicrobial compound. The results showed that blend films had higher tensile strength and elastic modulus and lower water vapor permeability than bilayer films (p<0.05). Bilayer films demonstrated as effective barriers against UV light and showed lower transparency values (p<0.05). FT-IR spectra indicated that interactions existed between chitosan and gelatin due to electrostatic interactions and hydrogen bond formation. However, the addition of LAE did not interfere in the network structure. Active films containing LAE (0.1%, v/v) inhibited the growth of four food bacterial pathogens including Listeria monocytogenes, Escherichia coli, Salmonella typhimurium, and Campylobacter jejuni. Chapter III focuses to develop films based on chitosan-gelatin blend enriched with cinnamon, citronella, pink clove, nutmeg, and thyme essential oils (1%, v/v) and evaluating their physical, optical, mechanical, water barrier and microstructural properties for active food packaging applications. The results confirmed intermolecular interactions between functional groups of the essential oils with the hydroxyl and amino groups of the chitosan-gelatin film network. The incorporation of different essential oils notably improved the UV barrier properties. The developed films, with special regards for those including thyme essential oil, were effective against four common food bacterial pathogens. Chapter IV aims to develop active films based on blending chitosan and polyvinyl alcohol enriched with LAE at different concentrations (1-10%, w/w). The results showed that high LAE levels negatively affected mechanical and water barrier properties. Addition of LAE improved UV barrier properties. The developed active films were effective against four common food bacterial pathogens.

Abstract:
Keratin has natural characteristic for applying in biomaterial field as a biocompatible matrix like tissue regeneration, proliferation, and cell adhesion or drug career in the shape of microcapsules or microsphere. Because of the amino acid inherent structure, keratin extraction needs to be well designed to meet the particular requirement for applying in desired applications such as integrate with different molecules, drug releases, wound healing or biocompatible film. Keratinous sources such as wool, feathers are valuable by-products that abundantly present in nature. Although wool has valuable material in especially in textile industry, massive amount of low-grade wool cannot be utilized in textile and inevitably end up as a waste stream. Because of high cystine content of keratin, solubilization and extraction of keratin is a problematic process compared with other natural polymers such as collagen and chitosan. Using keratin in different level especially in large-scale requires understanding final properties of keratin which is strongly depends on producing procedure.. The interest towards drug career and microcapsules based on non-toxic, biodegradable and biocompatible polymers, such as proteins, is increasing considerably. In this work, keratin from wool fibers was extracted with oxidation, reduction, sulfitolysis, and superheated water hydrolysis methods. The effect of each method on obtained keratin properties are discussed and particularly reported how each extracted keratin influenced by the extraction process. In particular, all different samples of extracted keratin were characterized by molecular weight determination, FT-IR and NIR spectroscopy, amino acid analysis, and thermal behavior and the archived data were compared with reporting of previous studies with the emphasis of advantage and limitation of each extraction method. In the other part of the study, special attention are given to produce microcapsule and film from keratin-based material in line with biomaterial application. Microcapsules were prepared using water-soluble keratin, known as keratoses, with the aim of encapsulating hydrophilic molecules. The obtained keratin via oxidizing extraction of pristine wool, were utilized as shell part of the microcapsules which produced by sonication method. Production of the microcapsules was carried out by a sonication method. The microencapsulation and dye encapsulation yields were obtained by UV-spectroscopy. In addition, morphological structure of microcapsules was studied by light microscopy, SEM, and AFM and thermal properties of microcapsules were investigated by DSC. The molecular weights of proteins analyzed with gel-electrophoresis indicates the extracted keratoses has suitable molecular weight range for bio-application, and also the results confirmed that the hydrophilic dye (Telon Blue) was introduced inside the keratoses shells. The final microcapsules diameter ranged from 0.5 to 4 µm. One part of the experimental work is dedicated to producing keratin blend film with polyvinyl alcohol (PVA). PVA has been chosen because of its biocompatible and biodegradable properties which make this polymer as a promising candidate in the bio-field area. Blend of Polyvinyl alcohol (PVA) and keratoses were prepared with the aim of producing bio-compatible material proper for film and fiber structure mainly to improve the mechanical properties of obtained keratoses. Aqueous solution of keratoses and PVA was prepared for solution casting method. Blended films were characterized by, SEM, FT-IR spectroscopy and Differential scanning colorimetry and tensile properties.

Magister Scientiae - MSc (Chemistry)
Blending polymers together offers researchers the ability to create novel materials that have a combination of desired properties of the individual polymers for a variety of functions as well as improving specific properties. The behaviour of the resulting blended polymer or blend is determined by the interactions between the two polymers. The resultant synergy from blending an intrinsically conducting polymer like polyaniline (PANI), is that it possesses the electrical, electronic, magnetic and optical properties of a metal while retaining the poor mechanical properties, solubility and processibility commonly associated with a conventional polymer. Aromatic polyamic acid has outstanding thermal, mechanical, electrical, and solvent resistance properties that can overcome the poor mechanical properties and instability of the conventional conducting polymers, such as polyaniline.

Abstract:
Polyaniline (PANI) an electronically conducting polymer, and its charge transfer complexes are interesting engineering materials due to their unique electronic conductivity, electrochemical behavior, low raw material cost, ease of synthesis and environmental stability in comparison with other conjugated polymers. The main disadvantage of PANI is its limited processability. Blending of conducting polymers with insulating polymers is a good choice to overcome the processability problem. In this study a solution-blend method is adopted to prepare conductive polyaniline/polyvinyl alcohol (PANI/PVA) blend films at various blend ratios. Interest in applications for polyaniline (PANI) has motivated investigators to study its electro mechanical properties, and its use in polymer composites or blends with common polymers. The work described here looks at the uniaxial deformation behavior of the conducting polymer films and the anisotropic dependency of electrical conductivity of the blend films exposed to static and dynamic loading conditions. The relation between mechanical strain, electrical conductivity and film microstructure is investigated on PANI/PVA blend films.

Abstract:
Bio based materials fall under the broad category of bio-products or bio-based products, which includes materials, chemicals and energy derived from renewable biological resources. This research shows the preparation of both, paper sheets with blend fillers of chitosan and rice starch and chitosan and rice starch films, which could be used as packaging material for a variety of applications. In this research, we used a blend mixture, different concentrations of chitosan and rice starch both in paper production and in films to investigate the optical properties of the obtained materials with a combination of ultrasonic treatment during the film formation. The research showed that the optical properties of the obtained packaging materials improved. It also showed that blend fillers of chitosan and rice starch are effective paper fillers in the preparation of cellulose mixture for bio based packaging materials and the optical properties are with slight changes. The investigation on the optical properties of the obtained paper samples during accelerated thermal showed that the ageing of paper with addition of chitosan and chitosan and rice starch blends had the same behaviour through the 72 hours of ageing. The ultrasonic treatment of the films improved transparency. The surface at untreated blend film was more uneven compared to chitosan and rice starch films, which improved after the treatment.

Abstract:
In this study, carboxymethyl cellulose, carrageenan-based films and a blend film with 1:1 concentration were prepared using the solvent casting method and the influence of various concentrations of jackfruit seed starch (0, 0.5, 1.0, 1.5, and 2 g) on its functional properties were investigated. The effect of jackfruit seed starch on strength properties such as tensile strength and elongation, as well as waterrelated characteristics such as water contact angle, water vapour permeability, and moisture content, were evaluated and compared with the results of the control blend films. FT-IR, TGA, SEM, XRD were performed to identify the functional group and its potential interactions, thermal stability, surface morphology and crystallinity of prepared films. The results suggests that addition of jackfruit seed starch from 0 to 1.5 g enhanced the tensile strength from 26.62 MPa to 33.26 MPa, but thereafter the tensile strength drops to 32.58 MPa and the elongation decreases. When compared to the carboxymethyl cellulose carrageenan control film, some physical parameters of the film, such as water vapour permeability and moisture content, decreased while thickness and contact angle increased significantly. The results of scanning electron microscopy exhibited rough and heterogeneous morphology for films with more starch content, while the control films exhibited smooth and homogenous structure. The presence of starch increased the crystallinity of all films, which attributed to improved thermal and mechanical stability of the prepared films.

Abstract:
The objective of this research is to prepare a hybrid biopolymer blend using PLA and PHBV with enhanced mechanical and thermal properties. Bio-based PLA and PHBV blends were prepared using the melt-mixing procedure. Tensile, FTIR, DSC, TGA, optical microscopy (OM), and scanning electron microscopy (SEM) tests were performed to investigate mechanical properties, bonding interaction, glass transition temperature, melting and crystalline enthalpy, thermal decomposition, and morphological analysis. Different percent (1, 2, and 3 wt%) of nanoclay was added to the system to observe the bonding interaction. It was observed that the crystallinity increases with increasing amount of nanoclay. The result showed that the tensile strength of PLA thin film and PHBV film was found to be 31.1 MPa and 14.41 MPa, respectively. Hence, PLA has better mechanical property than PHBV. On the other hand, thermal property of PHBV thin film was found to be better than that of PLA. To optimize both mechanical and thermal properties of PLA and PHBV hybrid biopolymer blend, using various combinations of PLA/PHBV including 25/75, 50/50 and 75/25 wt% a hybrid biopolymer blend was prepared. Among them, PLA-PHBV (75/25 wt%) with 2 wt% nanoclay resulted in the best outcome. The tensile strength of this prepared polymer blend was 29.34 MPa. Thermal analysis demonstrated two melting temperatures: 238.37 °C and 308.31 °C, respectively. Two glass transition temperatures were found from thermal tests which are the indication of the solution immiscibility. It had also been observed that the adding of nanoclay enhances tensile properties as well as thermal stability up to 2 wt%. It is revealed from the optical and SEM micrographs that the 2 wt% NC was dispersed uniformly throughout the resin blend.

Abstract:
Organic solar cells made from bi-layer thin-film heterojunctions having poly((2-methoxy-5-(2′-ethylhexyloxy)-p-phenylene)vinylene) (MEH-PPV) as an electron donor and fulleropyrrolidine derivatives as an electron acceptor were investigated. We synthesized soluble fulleropyrrolidine derivatives substituted different chain lengths for the organic solar cell. Due to the high solubility and sufficiently long chain length of fulleropyrrolidine derivatives, though those are monomers, a thin film (about 50 nm) could be fabricated individually by the spin-coating method. The fill factor of the bi-layer device was achieved to be 0.40, which is higher than that of the single-layer device by a polymer/fulleropyrrolidine derivative blend film of 0.29, due to the decrease of the recombination.
