Abstract:

A novel inorganic/organic nanocomposite film composed of Si nanoparticles (NPs) and poly-(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT–PSS) is obtained from a simple mechanical mixture of Si NPs powder and aqueous PEDOT–PSS solution. Employing this composite film as a counter electrode, dye-sensitized solar cell (DSSC) exhibits an efficiency of 5.7% and a fill factor of 0.51, which are much higher than these of DSSC using pristine PEDOT–PSS electrode (2.9% and 0.25, respectively). The improvements in the photovoltaic performance of the former are primarily derived from improved electrocatalytic performance of the electrode, as evidenced by electrochemical measurements, the composite electrode has lower impedance and higher electrocatalytic activity when in comparison with pristine PEDOT–PSS electrode. These improvements are primarily deriving from the increased electrochemical surface by the addition of Si NPs. The characteristics of Si NPs/PEDOT–PSS composite counter electrode reveal its potential for the use of low-cost and stable Pt-free counter electrode materials. In addition, the results achieved in this work also provide a facile and efficient approach to improve the photovoltaic performance of DSSCs using PEDOT–PSS electrodes.

Abstract:

A simple microfabrication technique for delivering macromolecules and patterning microelectrode arrays using desktop inkjet printer was described. Aqueous solution of nanoparticle of poly (3,4-ethylenedioxythiophene) (PEDOT) doped with polystyrene sulfonic acid (PSS) was prepared while its particle size, the surface tension, and the viscosity of the solution were adjusted to be suitable for deposition on a flexible cellulose nanocomposite substrate via inkjet printer. The statistical average of PEDOT: PSS particle size of 100 nm was observed. The microthickness, surface morphology, and electrical conductivity of the printed substrate were then characterized by profilometer, atomic force microscope (AFM), and four-point probe electrical measurement, respectively. The inkjet deposition of PEDOT: PSS was successfully carried out, whilst retained its transparency feature. Highly smooth surface (roughness ~23–44 nm) was achieved.

Abstract:

Poly (vinyl alcohol)-silver nanoparticles (PVA:AgNPs), and poly (vinyl alcohol)-silver nanoparticles-poly (3, 4-ethylene dioxythiophene)/poly (styrene sulfonate) (PVA:AgNPs: PEDOT/ PSS) were generated as ultra-fine electrospun fibers using the aligned fiber mat and aligned single fiber techniques. SEM and TEM were used to confirm the morphology, diameter size, and fiber alignment of the ultra-fine fibers. A two-probe technique was utilized to assess the electrical conductivity of the ultrafine fibers. The highest conductivity of PVA:AgNPs, (10 %w/v:0.75 %w/v) with a fiber diameter of 0.152 μm, with voltage applied at 17.5 kV within a 20 min collection period in the electrospinning process, was 43.20 S/cm; whereas the highest conductivity of PVA:AgNPs: PEDOT/PSS, (10 %w/v:0.25 %w/v:0.084 %w/v), with a fiber diameter of 0.158 μm and voltage applied at 17.5 kV within a 45 min collection period in the electrospinning process, was 92.18 S/cm.

Abstract:

Multiwalled carbon nanotubes (MWCNTs) were synthesized by the reduction of ethyl alcohol with sodium borohydride (NaBH4) under a strong basic solvent with the high concentration of sodium hydroxide (NaOH). Nanocomposites of different concentration of MWCNT dispersed in poly(3,4-ethylene dioxythiophene) polymerized with poly(4-styrene sulfonate) (PEDOT:PSS) were prepared and deposited on a flexible polyethylene terephthalate (PET) polymer substrates by the spin coating method. The thin films were characterized for their nanostructure and subsequently evaluated for their piezoresistive response. The films were subjected to an incremental strain from 0 to 6% at speed of 0.2 mm/min. The nanocomposite thin film with 0.1 wt% of MWCNT exhibits the highest gauge factor of 22.8 at 6% strain as well as the highest conductivity of 13.5 S/m. Hence, the fabricated thin film was found to be suitable for piezoresistive flexible strain sensing applications.

Abstract:

Herein, a facile route leading to good single-walled carbon nanotubes (SWCNT) dispersion or poly (3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) based single-piece nanocomposite membrane is proposed for trace determination of Cu2+ ions. The single-piece solid contact Cu2+-selective electrodes were prepared after drop casting the membrane mixture on the glassy-carbon substrates. The prepared potentiometric sensors revealed a Nernstian response slope of 27.8 ± 0.3 and 28.1 ± 0.4 mV/decade over the linearity range 1.0 × 10−3 to 2.0 × 10−9 and 1.0 × 10−3 to 1.0 × 10−9 M with detection limits of 5.4 × 10−10 and 5.0 × 10−10 M for sensors based on SWCNTs and PEDOT/PSS, respectively. Excellent long-term potential stability and high hydrophobicity of the nanocomposite membrane are recorded for the prepared sensors due to the inherent high capacitance of SWCNT used as a solid contact material. The sensors exhibited high selectivity for Cu2+ ions at pH 4.5 over other common ions. The sensors were applied for Cu2+ assessment in tap water and different tea samples. The proposed sensors were robust, reliable and considered as appealing sensors for copper (II) detection in different complex matrices.

Abstract:

Carbaryl is a broad-spectrum carbamate insecticide widely used to control pests on crops, trees and ornamental plants. Carbaryl residues in fruits and vegetables and other foods can accumulate in the human body and damage human health. Therefore, it is very essential to establish a sensitive and reliable method for determination of carbaryl. Black phosphorene nanosheets (BPNPs) modified glassy carbon electrode was herein prepared using poly(3,4-dioxyethylenethiophene)-poly(styrene sulfonate) (PEDOT: PSS) as both membrane and stabilizer. The nanocomposites (BP-PEDOT: PSS) were synthesized by combining BP at the ratio of PEDOT: PSS, which improved conductivity and stability of BP. In order to enhance the electrochemical signal and build the carbaryl aptamer sensor, the surface of BP-PEDOT: PSS was modified by Au nanoparticles (Au NPs). The carbaryl aptamer modified with sulfhydryl groups was immobilized in the outer layer of Au NPs, and the target carbaryl was specifically recognized and captured by carbaryl aptamer and adsorbed on the electrode surface, thus causing changes in the interfacial electrochemical signal. The conditions were optimized and characterized by cyclic voltammetry (CV), and linear equation was obtained as ΔI(μA) = −11.35logC−29.70, R2 = 0.997. The detection range was 0.01 ng/mL–10 μg/mL, with a limit of detection of 7.0 pg/mL.

Abstract:

This research project produced two fabricated ultrafine conductive polymeric fibers. The first fiber was fabricated from a polymer and conductive polymer solution, and the second was fabricated from a polymer and metal nanoparticle/ nanocomposite. The resulting fibers were characterized and analyzed. For all fiber samples, the ultrafine polymeric fibers were fabricated using polyvinyl alcohol (PVA). The conductive polymer used in the first fiber sample was poly (3,4-ethylenedioxythiophene)/ polystyrene sulfonate (PEDOT/PSS). The conductive nanoparticles used in the second fiber sample were silver nanoparticles (AgNPs). The ultrafine conductive polymer fibers and the ultrafine conductive nanoparticle fibers were fabricated using an electrospining process. During the fabrication process of each fiber sample, different concentrations of either PEDOT/PSS, for fiber sample one, or AgNPs, for fiber sample two, were combined in PVA solution. Using optimal conditions, ultrafine fibers were fabricated at intervals of 5 min for the creation of random fibers, and intervals of 20 min for the creation of aligned fiber mats. The resulting fibers ranged from 0.1 μm to 0.2 μm in diameter. After characterization and analysis of the conductive ultrafine polymeric fibers, using either the PVA:PEDOT/PSS compound or the PVA:AgNPs compound, both samples produced greater conductive capacities with greater concentrations of solution. For the random fiber samples, the conductive capacity was sporadic. However, the ultrafine fiber mats (PVA:AgNPs) supported a capacity from 3.64 S/cm to 10.64 S/cm, and the PVA:PEDOT/PSS ultrafine fiber mats supported a capacity from 4.49 S/cm to 7.08 S/cm.

Abstract:

Recently, the conjugated polymer -- inorganic nanocomposites have been increasingly studied because of their enhanced optical and electronic properties as well as their potential application in developing optoelectronic devices. In this study nanocomposite materials thin films based on poly [2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and nanocrystalline TiO\(_{2}\) (nc-TiO\(_{2}\)) have been fabricated. The photoluminescence (PL) spectra of pure MEH-PPV and nanohybrid films have shown that the excitation at a 377 nm wavelength leads to the strongly enhanced performance in photoluminescent intensity due to the compositions of TiO\(_{2}\) component. Current-voltage (I-V) characteristics of multi-layer device Al//MEH-PPV:nc-TiO\(_{2}\)//PEDOT: PSS//ITO//glass were investigated. The results show that the hybrid MEH-PPV:nc-TiO\(_{2}\) materials with high concentrations of TiO\(_{2}\) (>25%) can be expected to be a good candidate for photovoltaic solar cell applications whereas those with lower concentrations of TiO\(_{2}\) are more suitable for organic light-emitting diodes (OLEDs).

Abstract:

The performances of organometallic halide perovskite-based solar cells severely depend on the device architecture and the interface between each layer included in the device stack. In particular, the interface between the charge transporting layer and the perovskite film is crucial, since it represents both the substrate where the perovskite polycrystalline film grows, thus directly influencing the active layer morphology, and an important site for electrical charge extraction and/or recombination. Here, we focus on engineering the interface between a perovskite-polymer nanocomposite, recently developed by our group, and different commonly employed polymeric hole transporters, namely PEDOT: PSS [poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)], PEDOT, PTAA [poly(bis 4-phenyl}{2,4,6-trimethylphenyl}amine)], Poly-TPD [Poly(N,N′-bis(4-butylphenyl)-N,N′-bis(phenyl)-benzidine] Poly-TPD, in inverted planar perovskite solar cell architecture. The results show that when Poly-TPD is used as the hole transfer material, perovskite film morphology improved, suggesting an improvement in the interface between Poly-TPD and perovskite active layer. We additionally investigate the effect of the Molecular Weight (MW) of Poly-TPD on the performance of perovskite solar cells. By increasing the MW, the photovoltaic performances of the cells are enhanced, reaching power conversion efficiency as high as 16.3%.

Abstract:

The electromagnetic nanocomposites with a core-shell structure are synthesized by in situ chemical oxidative polymerization. The Co doped Fe3O4magnetic particles (Co-Fe3O4) act as the core and poly (3,4-ethylenedioxythiophene)-poly (sodium-p-styrenesulfonate) (PEDOT-PSS) as the conductive polymer shells. The morphology, structure, crystallinity, conductive and magnetic properties were studied by transmission electron microscopy (TEM), Scanning electron Microscope (SEM), Fourier Transform Infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), four-probe conductivity meter and vibrating sample magnetometer (VSM). It is found that the core-shell nanocomposites exhibit controllable electromagnetic properties by adjusting the molar ratio of Co-Fe3O4to EDOT monomer.

Abstract:

An Electronic Tongue or E-tongue can be defined as a bio-mimicking sensor generally meant to mimic the ability to taste sweet, sour, bitter, and salty compounds and quantify each of these compounds. In an E-tongue, there are counter/sensing electrodes and a reference electrode. The current generated between the electrodes or the change in the resistance of the electrodes is used as an input for a mathematical model and with the help of computer simulations the taste or the nature of the compound is analyzed. This type analysis is usually seen in systems using electrodes modified with advanced nanocomposites such as graphene, PEDOT: PSS, Molybdenum Disulphide, etc. Here the tendency of the sample to resist the flow of electrons from the working electrode to the reference electrode is measured with input signals constantly varying in frequency and amplitude. This article discusses the methods and construction of E-tongues as well as their application across various fields. We shall also discuss the experimental details of various types of E-Tongue used in different solutions and their results. E-tongues have an important role in wine tasting today as their ability to breakdown the compound and individually analyze the components of the compounds with excellent accuracy is unparalleled.

Abstract:

Polyethylene dioxythiophene and polyethylene sulfonic acid (PEDOT/PSS) composite is gathering attention as an organic transparent conductive film material. However, it requires a core-shell structure in which conductive PEDOT is covered with insulating PSS. Providing film formability and a carrier to PEDOT, the PSS shell hinders carrier conduction as an insulating barrier. In this study, we realized that creating a macro-separated PEDOT/PSS composite by using a polyelectrolyte brush substrate and in-situ PEDOT polymerization without the PSS barrier increases durability and conductivity in comparison with commercially available PEDOT/PSS film, achieving a conductivity of 5000–6000 S/cm.

Abstract:

This study evaluated the wound-healing activity of a polymer, Poly(3,4-ethylenedioxythiophene):poly-(styrene sulfonate) (PEDOT: PSS), and determined its mechanism based on angiogenic activity in a full-thickness excision wound model in Spraque Dawley (SD) rats. Administering PEDOT: PSS (1.6) 1.5 ppm at a dose of 50 mg/kg/day significantly improved wound healing in the SD rats on the eleventh day after the incision was created. PEDOT: PSS-treated animals presented no anti-inflammatory skin effects; however, there was an increase in angiogenic behavior. VEGF was found to be significantly elevated in the PEDOT: PSS-treated groups seven days post-incision. However, only a higher concentration of PEDOT: PSS increased TGF-β1 expression within the same time frame. Our results showed that PEDOT: PSS enhances wound healing activity, mainly in terms of its angiogenic effects. In this paper, we describe the highly conductive macromolecular material PEDOT: PSS, which demonstrated accelerated wound-healing activity in the animal incision model. The results will further provide information regarding the application of PEDOT: PSS as a dressing for medical use.

Abstract:

The contact formed between aluminum and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid) (PEDOT-PSS) derivatives was studied using x-ray photoelectron spectroscopy. The aluminum/PEDOT-PSS contact contains an interfacial layer formed by chemical reactions between aluminum and mainly poly(styrenesulfonic acid) (PSSH). These chemical interactions were studied with the help of model systems (PSSH, benzenesulfonic acid, and sodium benzenesulfonate). The preferred reaction site of aluminum is the SO3− and SO3−H+ groups of the PSS chains, giving rise to C-S-Al(-O) and C-O-Al species. The resulting contact formed consists of an insulating aluminum/PSS layer and a thin region of partially dedoped PEDOT-PSS. There is significant aluminum diffusion into films of the highly conducting form of PEDOT-PSS that have substantially less PSS at the surface. Hence, no (thick) aluminum/PSS layer is formed in this case, though the PEDOT chains close to the aluminum contact will still be partially dedoped as for the aluminum/PEDOT-PSS case.

Abstract:

This article demonstrates changes in the structures of poly (3,4-ethylene dioxythiophene): polystyrene sulfonate (PEDOT: PSS) with the addition of organic additives. The mechanisms of PEDOT: PSS are analyzed using X-ray photoelectron spectroscopy (XPS), cross-sectional images obtained from scanning electron microscopy (SEM), and contact angles. In this paper, a bond-breaking reaction and phase separation are successfully found to occur between PEDOT: PSS molecules and the organic additives. Our research also finds that this bond-breaking reaction and phase separation exist in the PEDOT: PSS–sorbitol–maltitol film at the same time. The addition of organic additives will improve the optical properties and the moisture stability of PEDOT: PSS films.

Abstract:

Conducting polyacrylonitrile (PAN) nanofiber mats were prepared by dipping non-woven nanofiber mats of PAN in the solution of poly(3,4-ethylenedioxythiophene)/poly(4-styrenesulfonate) (PEDOT/PSS). PAN nanofiber mats were fabricated via the electrospinning process. The solvent used for PEDOT/PSS was ethylene glycol and isopropanol. The morphology of the resulting PAN nanofibers and the coating layers was investigated using SEM analysis. The electrical conductivity of PEDOT/PSS coated PAN nanofiber mats was measured by the four-point probe method, for different concentrations of solvent in the PEDOT/PSS solution. An addition of ethylene glycol resulted in higher electrical conductivity of the coated mats than that of isopropanol. The resistive humidity sensing properties were also investigated. The device reproducibility was presented by vapor adsorption/desorption dynamic cycles. The reproducibility of the PEDOT/PSS coated mats was superior to that of neat PEDOT/PSS films. The response sensitivity of coated mats using isopropanol as solvent was higher than that using ethylene glycol.

Abstract:

The composite conductive fibers based on poly (3,4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT-PSS) blended with polyacrylonitrile (PAN) were prepared via a conventional wet spinning process. The influences of PEDOT-PSS content on the electrical conductivity, thermal stability and mechanical properties of the composite fibers were investigated. The fiber with 1.83 wt% PEDOT-PSS showed a conductivity of 5.0 S/cm. The breaking strength of the fibers was in the range of 0.36-0.60 cN/dtex. The thermal stability of the PEDOT-PSS/PAN composite fibers was similar to but a slightly lower than the pure PAN. The XRD results revealed that both pure PAN and the PEDOT-PSS/PAN composite fibers were amorphous phase, and the crystallization of the latter was lower than the former.

Abstract:

A novel kind of poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT/PSS) composite was synthesized through chemical oxidation polymerization in the presence of fluorescent yellow GG (FYGG) as the functional co-dopant and Poly(vinyl alcohol) as the film-forming additives. The as-prepared composite was found combined with fluorescent function and electrochromic property. Film of the PEDOT/PSS-FYGG composites switches from green in the reduction state to blue-green in the oxidized state, which is different from the pure PEDOT/PSS of light blue (-0.2V) and dark blue (0.8V). Because of the big molecule of FYGG as the dopant, the response time reaching 90% of the full optical contrast of PEDOT/PSS-FYGG was 1.77s for the coloration process and 1.78s for the reverse bleach process, which is a little slower than the pure PEDOT/PSS. Additionally, PEDOT/PSS-FYGG film presents a good stability. It is shown that acid dye doping is an effective method to broaden the color change range of the electrochromic mateials.

Abstract:

Abstract The chronoamperometric and coulometric response of solid contact ion-selective electrodes (SCISEs) for the detection of divalent cations was investigated in order to provide a more complete description of the mechanism of the recently introduced coulometric transduction method for SCISEs. The coulometric transduction method has earlier been employed only for SCISEs that were selective to monovalent ions. The SCISEs utilized poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(styrene sulfonate) (PSS−) as the solid contact (ion-to-electron transducer). PEDOT(PSS) was electrodeposited on glassy carbon and covered with plasticized PVC-based ion-selective membranes (ISMs) that were selective towards divalent cations (Ca2+, Pb2+). In contrast to earlier studies, the results obtained in this work show that the coulometric response for the Pb2+-SCISE was limited mainly by ion transport in the PEDOT(PSS) layer, which was not the case for the Ca2+-SCISE, nor was it observed earlier for the monovalent ions. The exceptional behavior of the Pb2+-SCISE was explored further by electrochemical impedance spectroscopy, and it was shown that the effective redox capacitance of PEDOT(PSS) was significantly higher for the Pb2+-SCISE than for the Ca2+-SCISE although the polymerization charge of PEDOT(PSS) was the same. The slow transport of Pb2+ in PEDOT(PSS) was tentatively related to complexation between Pb2+ and PEDOT(PSS).

Abstract:

In this study, we fabricated a planar Si/PEDOT: PSS heterojunction solar cell using three different solvents—ethylene glycol, acetonitrile, and dimethyl sulfoxide—to find the best one. The fabricated samples were characterized by diffuse reflectance spectroscopy, scanning electron microscopy, X-ray diffraction, and current–voltage. Diffused reflectance spectrum analysis showed reduced reflectance compared to the bare silicon wafers. The absorbance spectrum shows the change in absorption of the Si-coated PEDOT: PSS which was more than a 50% increase in the UV region, and for the EG sample, there was a 20% increase in the entire visible spectrum. This indicates that the solvent plays a major role in the bandgap between the Si and Si/PEDOT: PSS. Scanning electron microscope (SEM) was used to examine the surface morphology of Si/PEDOT: PSS as agglomerated, island-formed surfaces and carbon-layered Si-PEDOT: PSS. Cross-sectional images show the thickness of the PEDOT: PSS layer on the silicon wafer surface. The X-ray diffraction (XRD) pattern shows the characteristic peaks for silicon (69.5°), and Si/PEDOT: PSS shows a forbidden Si (200) peak at 32°. Current–voltage measurements have shown the characteristic diode curve for all fabricated cells. This characteristic diode curve indicated the presence of a heterojunction. Ethylene glycol-containing cells showed current output as 0.2 μA with Voc of 0.2 V.

The addition of sorbitol and maltitol can disperse the micelles of PEDOT: PSS. The mechanism of the bond-breaking reaction was investigated and a model for the bond-breaking reaction is also proposed. Furthermore, multiple formic acid treatments were found to reduce the PSS content of PEDOT: PSS, resulting in an enhancement in conductivity (4.2 × 104 S/m).
