Purpose. Evaluation influence structural state polymer phase on the response voltage and coefficient nonlinearity of a multilayer varistor based on zinc oxide. Methodology. Zinc oxide consisted of 97% zinc oxide and 3% total oxides of Bi2O3, Co3O4, MnO2, B2O3, SbO3, ZrO2, Al2O3. At a temperature of 1573°K, the synthesis of semiconductor ceramics based on Zinc oxide was carried out. For composite of thermoplastic polymers and Zinc oxide, non-polar and polar polymers, high pressure polyethylene and polyvinylidene fluoride were used. The composites were obtained by hot pressing at the melting temperature of the polymer phase and a pressure of 15 MPa. After that, using silver paste, measuring electrodes 10 mm in diameter were applied to the surface of the synthesized samples, and then current–voltage characteristics were measured. Modification of composites under action of gas-discharge plasma was carried out in a special cell that creates a dielectric-gas-composite system. The structure of the composites was studied by X-ray diffraction analysis and IR spectroscopy. Findings. The obtained experimental results show that the size of the particles of the inorganic phase significantly affects the current-voltage characteristics of the composite varistor: at a given thickness of the composite varistor, the operation voltage decreases markedly, and the nonlinearity coefficient increases. Numerous experimental results obtained by us show that the impact of electric discharge plasma on the polymer Zinc oxide-composite leads to a significant change in the permittivity and the concentration of local levels at the interface of the composite. The results research showed that effect electrical plasma on the opening voltage depends on the polarity of polymer matrices. Moreover, plasma processing itself significantly changes the structure of the polymer phase at composite. Originality. The magnitude of the potential barrier at phase boundary is mainly determined by the volume fraction and size of the main structural element of ZnO ceramics. Changing the structural state of the polymer matrix allows the adjust response voltage and coefficient nonlinearity of volt-ampere characteristic of the multilayer varistor. Practical value. The discovered development of electron-ion processes at polymer phase of the varistor indicates the need to take into account change in its service characteristics from the duration and intensity of use. The result obtained has a certain practical significance, since it indicates not only the reason for the change in properties, but also the need to develop measures to increase the service life of the varistor.

Streszczenie:

A series of novel Zinc Oxide (ZnO) copolymer composites films with different Zinc Oxide concentration were prepared through incorporation of pre-made Zinc Oxide particle in to copolymer epoxy poly(dimethyl acrylamide). The copolymer epoxy poly(dimethyl acrylamide) was synthesized by free radical polymerization to disperse the Zinc Oxide nanoparticles. The Zinc Oxide nanoparticles with the diameter of 19 nm–35 nm were synthesized from zinc nitrate via a wet chemical method. The aim of the work is to develop a new method/process/material for the dispersion of Zinc Oxide nanoparticles and testing the performance of these composites films. Thermo gravimetric analysis show that Zinc Oxide nanoparticles were successfully incorporated into the polymer matrix and the Zinc Oxide copolymer composites have a good thermal stability. The micro structural analysis also show newly synthesized polymer disperse the nanoparticles well as evidenced by Scanning Electron Microscopy (SEM) analysis. The uniformly dispersed Zinc Oxide nanoparticle in the polymer matrix and the particles almost remained in their original shape and size even after incorporation in the polymer matrix. Fourier transform infrared spectroscopy (FT-IR) shift of the copolymer adsorbed Zinc Oxide nanoparticles confirmed that polymer molecules chain was anchored on the surface of the nanoparticles.

ZnO oxide Nanoparticle and ZnO oxide with Montmorillonite nanocomposite were prepared by an environmentally friendly, efficient, and inexpensive method that was synthesized using the chemical method. ZnO nanoparticles as an effective antibacterial material were immobilized on the surface of montmorillonite (MMT). The objectives of this paper are to summarize our research activities in (a) developing processes to dispersenanomaterials (undoped and doped zinc oxide powders) in the polymers matrix, (b) using X-ray diffraction (XRD), Fourier Transform Infra-Red Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Thermo Gravimetric Analysis (TGA) techniques to characterize polymer matrix structures, (c) studying structure-property relationship of these types of new materials, and (d) evaluating the antibacterial performance of these materials for different applications. The results showed that the ZnO nanocomposite was uniformly dispersed in the polymer matrix and the particles remained their average size (20 - 150 nm) before incorporation into the polymer matrix.

Streszczenie:

On the basis of a direct current magnetron, a technology has been developed for producing nanoscale-oriented nanorods from zinc oxide on an acrylic polymer. The technology makes it possible to achieve different filling of the surface with zinc oxide nanorods. The nanorods is partially fused into the polymer; the cross section of the nanorods is rather close to an elongated ellipse. It is shown that, with intense abrasion, no delamination of the nanorods from the acrylic polymer is observed. The zinc oxide nanorods abrades together with the acrylic polymer. Zinc oxide nanorods luminesces with the wavelength most preferable for the process of photosynthesis in higher plants. It was shown that plants grown under the obtained material grow faster and gain biomass faster than the control group. In addition, it was found that on surfaces containing zinc oxide nanorods, a more intense formation of such reactive oxygen species as hydrogen peroxide and hydroxyl radical is observed. Intensive formation of long-lived, active forms of the protein is observed on the zinc oxide coating. The formation of 8-oxoguanine in DNA in vitro on a zinc oxide coating was shown using ELISA method. It was found that the multiplication of microorganisms on the developed material is significantly hampered. At the same time, eukaryotic cells of animals grow and develop without hindrance. Thus, the material we have obtained can be used in photonics (photoconversion material for greenhouses, housings for LEDs), and it is also an affordable and non-toxic nanomaterial for creating antibacterial coatings.

Polymeric blends of Poly (p-anisidine) with ZnO nanoparticles was prepared by chemical oxidative polymerization. Zinc oxide doped PPA polymer nanocomposite (ZPPA) and Magnesium doped Zinc oxide PPA polymer nanocomposite (MZPPA) were synthesized with the addition of semiconductor metal oxide to the polymeric solution. The X-ray diffraction studies of ZnO nanoparticles showed hexagonal wurzite structure. The surface morphological study also confirms the formation of hexagonal structured nanoparticles. The peak for Magnesium and Zinc in EDS spectra confirms the formation of Magnesium doped polymer nanocomposite. The addition of ZnO/MgZnO onto PPA conducting polymer showed agglomeration of semiconductor material results in spherical shaped polymer nanocomposite and irregular overlapping over the PPA polymeric surface. The electrochemical conductivity studies suggested that the doped PPA conducting polymeric blends showed enhanced conductivity nature.

The hybrid polymer materials of nano-zinc oxide were synthesized via miniemulsion polymerization technique. Zinc oxide nanoparticles were encapsulated by polystyrene to introduce multi-function to the hybrid nano-zinc oxide. The contents of zinc oxide particles in the hybrid nano-zinc oxide were various from 1wt% to 40wt%. The particles sizes of hybrid nano-zinc oxide were determined by using dynamic light scattering. It was showed that the particle size of the hybrid nano-zinc oxide was in the range of 124-205nm. Scanning electron microscopy was employed to determine the topography and morphology of hybrid nano-zinc oxide. The crystal structure of hybrid nano-zinc oxide were explored by X-ray diffraction spectroscopy.

Changing the molecular weight produced no effect of the crystallinity of ZnO nanoparticles if similar molarity of ethylene glycol unit were used. However, the use of high molecular weight of polymers tended to reduce the size of nanoparticles, which implied to the enhancement in the luminescence spectra due to increasing in the particle number concentration.

Bulk heterojunction photovolataic devices based on blends of conjugated polymer poly (2- methoxyl-5- dodecoxyl p-phenyl vinylene) (PMODOPV) as electron donor and crystalline ZnO nanowires as electron acceptor have been studied. We show that photovoltaic devices using zinc oxide nanowires overlaid with conjugated polymers give improved performance compared with devices made only from polymer. The improvement is consistent with improved electron transport perpendicular to the plane of the film. Solar power conversion efficiency of 1.37% were achieved under AM1.5 illumination .

A composite polymer consisting of polyaniline (PANI) was synthesised via oxidative polymerisation by varying concentrations of transitional metal oxides and the presence of a hydrogen dissociation catalyst, palladium (Pd). The metal oxides chosen for this study were tungsten oxide (WO3) and zinc oxide (ZnO). The composite polymer samples were characterised using Fourier transform infrared (FTIR) spectroscopy where ultraviolet-visible (UV-Vis) spectroscopy was used to observe the optical changes of the thin films due to exposure to hydrogen. The FTIR spectra obtained confirmed the synthesis of PANI composite. Based on the UV-VIS analysis, PANI-ZnO composite polymer showed the highest difference in peak intensity before and after exposure to hydrogen with 11.4% difference.

Streszczenie:

Organic photovoltaics (OPVs) have received a great deal of focus in recent years as a possible alternative to expensive silicon based solar technology. Current challenges for organic photovoltaics are centered around improving their lifetimes and increasing their power conversion efficiencies. One approach to improving the lifetime of such devices has been the inclusion of inorganic metal oxide layers, but interaction between the metal oxides and common conjugated polymers is not favorable. Here we present two methods by which the interactions between polythiophenes and nanostructured ZnO can be made to be more favorable. Using the first method, direct side on attachment of polythiophene to ZnO nanowires via chemical grafting, we demonstrate chemical linkage between the polymer and ZnO phases. The attachment was confirmed to affect the morphological properties of the polymer layer as well, inducing highly ordered regions of the polymer at the ZnO surface via chemical attachment and physical adsorption. Using the second method to improve polythiophene ZnO interactions, we have functionalized ZnO nanowires with organic molecules that favorably interact with conjugated polymer and organic solvents. Photovoltaic devices were made using a blended active layer of functionalized ZnO nanowires and P3HT. Electrical analysis of the resultant devices concluded that the devices were functional photovoltaic cells and isolated the dominant loss mechanisms for further device improvement.

The performance and life time of organic solar cells are critically dependent on the properties of active layer materials and device interfaces. In this manuscript, we developed new organic-inorganic hybrid materials to create intimate contact between donor and acceptor phases and facilitate the interfacial electronic charge transfer through the device. First, the synthesis of versatile triethoxysilane-terminated poly(3-hexylthiophene) P3HT for direct anchoring (grafting-onto) in one step procedure to various metallic oxides was reported. Electro-optical analysis showed an efficient charge transfer from the polymer to nanoparticles; suggesting that these materials are suitable candidates for photovoltaic application. In the second part, we demonstrate for the first time the elaboration of low band gap polymer brushes on metallic oxide surfaces via surface initiated step growth polymerization (grafting-through). In both cases, a higher grafting density, better packing of polymer chains and enhanced optical properties were observed due to the grafting methodology and polymer characteristics. Finally, P3HT brushes were elaborated on indium tin oxide surface (ITO) as hole transporting layer of organic solar cells. Photovoltaic performances showed that P3HT self-assembled monolayer (SAMs) could be promising alternatives to PEDOT:PSS
Les performances et la durée de vie des cellules solaires organiques sont fortement dépendantes de la qualité des matériaux de la couche active et des interfaces dans le dispositif. Dans ce manuscrit, nous avons développé des nouveaux matériaux hybrides organiques-inorganiques pour favoriser le contact entre les matériaux donneur/accepteur d’électrons et ainsi faciliter le transfert de charges à travers le dispositif. Tout d'abord, la synthèse de poly(3-hexylthiophène) P3HT fonctionnalisé par le triéthoxysilane a permis le greffage direct (« grafting-onto ») sur des oxydes métalliques. L’analyse des propriétés électro-optiques montre un transfert de charge efficace du polymère aux nanoparticules; ce qui suggère que ces matériaux sont des candidats potentiels pour l'application photovoltaïque. Dans la deuxième partie, nous avons montré pour la première fois, l’élaboration de brosses de polymères dits à faible bande interdite sur des surfaces d’oxydes métalliques par la technique « grafting-through ». Une densité de greffage élevée, un meilleur empilement des chaines de polymères et des propriétés optiques améliorées ont été obtenus grâce à la technique de greffage et aux caractéristiques du polymère greffé. Enfin, des brosses de P3HT ont été élaborées sur la surface d’oxyde d'indium et d’étain (ITO) en tant que couche de transport de trous de cellules solaires organiques. Les performances photovoltaïques ont montré que les monocouches auto-assemblées de P3HT (SAM) peuvent être une alternative au PEDOT: PSS

The purpose of this thesis work is to design and fabricates organic-inorganic hetero junction White Light Emitting Diode (WLED). In this WLED, inorganic material is n- type ZnO and organic material is p-type conjugated polymer. The first task was to synthesise vertically aligned ZnO nano-rods on glass as well as on plastic substrates using aqueous chemical growth method at a low temperature. The second task was to find out the proper p- type organic material that gives cheap and high efficient WLED operation. The proposed polymer shouldn’t create a high barrier potential across the interface and also it should block electrons entering into the polymer. To optimize the efficiency of WLED; charge injection, charge transport and charge recombination must be considered. The hetero junction organic-inorganic structures have to be engineered very carefully in order to obtain the desired light emission. The layered structure is composed of p-polymer/n-ZnO and the recombination has been desired to occur at the ZnO layer in order to obtain white light emission. Electrical characterization of the devices was carried out to test the rectifying properties of the hetero junction diodes.

Zinc xanthates are active catalysts in stereoregular polymerization of propylene oxide and markedly more stable than that of known classical stereoregular catalysts. But steric control of zinc xanthates is weaker. To find more effective catalyst systems the isopropyl xanthates of Cu, Pb, Ni, Fe, Al and Sn are investigated and only copper (Cu(isoPr)Xt) and tin (Sn(isoPr)Xt) isopropyl xanthates were appeared to be active, but Cu(isoPr)Xt yielded only low molecular weight product. Therefore Sn(isoPr)Xt system was investigated in detail in polymerization of propylene oxide (PO). Polymerization of PO with this catalyst produced two contrasting polymers
high molar mass, crystalline (K-polymer) and low molar mass (D-polymer). Formation of double bonds in D-polymer was thought to be due to as an anionic process. Polymerization reactions were studied by changing polymerization conditions and reacting catalyst with predetermined amount of water. It&

s found that Sn(isoPr)Xt have considerably low efficiency than that of Zn(isoPr)Xt catalyst. The yield linearly increases by increasing catalyst concentration. The propagation is competed by termination or transfer process hence overall activation energy is negative. Some mechanistic features of this system was also discussed. The catalytical activity of carbamates in this field has also been reported, without any information about catalytical efficiency and stereoregularity of the process. Therefore zinc diethyl dithiocarbamate was also studied and found as an active catalyst in stereoregular polymerization but it showed weaker efficiency in the PO polymerization than that of Zn(isoPr)Xt catalyst (about 12 times weaker).

This thesis presents an investigation into the factors affecting the morphology of hybrid inorganic/organic photoactive layers used in photovoltaic cells. Although optimisation of the organic (polymer) phase has received substantial attention, research into the morphology of the inorganic phase (semiconducting nanocrystals) remains limited. It is believed that there is a strong link between the morphology of the final photoactive film and the quality of the initial nanocrystal dispersion. To this end, two nanocrystal systems were investigated; zinc oxide (ZnO) and lead sulphide (PbS). ZnO nanocrystals were synthesised and found to possess reproducible characteristics. It was determined that colloid stability was initially dependent upon the presence of acetate groups bound to the surface, which in turn required a small quantity of methanol to be present in the organic dispersant. It was also discovered that while methanol evaporated readily from the surface of the nanocrystals, another molecule, 1-propylamine (1-PA), did not. Further investigations showed that while methanol only weakly physisorbed to the surface of ZnO nanocrystals, 1-PA formed strong, dative covalent bonds with Zn2+, preventing evaporation despite a low boiling point. Subsequent investigations into the effects of different ligands upon colloid stability found that amine-based groups typically possessed superior stabilising capabilities compared to alcohol-based analogues. The characteristics of nanocrystal / polymer blends were also investigated. It was determined that the nanocrystal dispersion became unstable at higher concentrations of polymer due to depletion aggregation. Films of nanocrystal / polymer blends were cast from dispersions containing either alcohol or amine-based ligands, and it was observed that dispersions stabilised with 1-PA possessed smooth morphologies on the micrometer scale. Investigations at the nanometer scale, however, revealed aggregates large enough to favour recombination.The latter half of this thesis regards the characterisation of PbS nanocrystals and investigations into triggered aggregation. It was determined that while PbS nanocrystals possessed reproducible characteristics, the stabilising molecule, oleic acid (OA) was insulating. The effects of exchanging the OA groups for a shorter ligand, butylamine (BA) were investigated.Finally, PbS nanocrystals were treated with a bidentate ligand, 1,2-ethanedithiol (EDT) to induce triggered aggregation. It was observed that the system was highly sensitive to the concentration of EDT in dispersion, forming small, relatively dispersed aggregates at low [EDT], and micrometer-sized crystalline structures at high [EDT]. The characterisation and entrapment of these nanocrystal structures within semi-conducting polymer films is also discussed.

This article discusses the structural, electronic, magnetic, and transport properties of carbon-fullerene-based polymers. In particular, it examines the defect-induced ferromagnetism of the C60-based polymers and its analog in the case of non-traditional inorganic materials. It first reviews the computational methods currently used in the literature, highlighting the pros and cons of each one of them. It then considers the defects associated with the ferromagnetism of the C60-based polymers, namely carbon vacancies, the 2 + 2 cycloaddition bonds and impurity atoms, and their effect on the electronic structure. It also evaluates the effect of codoping and goes on to describe the electronic, magnetic and transport properties of the rhombohedral C60-polymer. Finally, it looks at the origin of magnetic coupling among the magnetic moments in the rhombohedral C60-polymer and provides further evidence for the analogy between the magnetism of the rhombohedral C60-polymer and zinc oxide.

Streszczenie:

To reinforce the protection of the steel against corrosion, surface treatments are carried out (conversion coating, for example) followed most often by the application of an organic coating. The adhesion of the conversion layer or of the polymer to the metal oxide layer must be optimal. However, in adhesion phenomena, the dispersive interactions and acid-base type interactions between the surface sites of the two materials in contact play an important role. In order to understand and predict adhesion, it is necessary to quantify these interactions. The authors proposed in this research to study the dispersive and Lewis acid-base interactions between the oxides present on the surface of galvanized sheets and model organic molecules by using the inverse gas chromatography (IGC) at infinite dilution and the new models recently published. The obtained results proved that the dispersive surface energy of the Monogal surface is greater than that of zinc oxide surface, but much lower than the zinc hydroxide surface. It was also shown that the Monogal exhibited the lower Lewis acid-base properties.

Streszczenie:

With the rapid developments in polymer matrix nanocomposites, there is growing interest in understanding their behaviors under adverse service conditions. A simple literature search will show the tremendous number of publications on montmorillonite (MMT) filled nanocomposites. It is therefore natural to see that the degradation behaviors for MMT filled nanocomposites have also received a number of detailed studies [1–10]. It was observed that by introducing MMT particles into LDPE [5] and PP [6, 7] matrices, the rate of photo-oxidative degradation was much faster than the corresponding unfilled matrixes. Furthermore, the dispersion state of the MMT particles did not seem to have influence on the photo-degradation rate [5].

Streszczenie:

All-solution processed, low-temperature zinc oxide nanowire network transistor fabrication was demonstrated by combining 1) source-drain electrode fabrication by direct nanoimprinting of metal nanoparticle solution and 2) zinc oxide nanowire network based channel synthesized by a simple hydrothermal approach in water. This simple process can produce high resolution metal contact transistors with inorganic semiconductor nanowire active material in a fully maskless sequence, eliminating the need for lithographic and vacuum processes. The temperature throughout the processing was under 140°C, which will enable further applications to electronics on low-cost, large-area flexible polymer substrates.
