Electrospun fibers of 7-methyl-4-phenyl-8-(4’-methoxy)phenylazopyrazolo[5,1-c][1,2,4]triazine-3-carboxylic acid ethyl ester (PCA-4) and 7-methyl-4-phenyl-8-(2’-methoxy)phenylazopyrazolo[5,1-c][1,2,4]triazine-3-carboxylic acid ethyl ester (PCA-2) were produced using electrospinning technique. Poly(methylmethacrylate) (PMMA) was used as support elect...

In this study, the effects of silane‐treated nano‐CaCO3 particles on the flexural, Mode‐I, Mode‐II and interlaminar shear strength (ILSS) properties of carbon fiber/epoxy composites are investigated experimentally. The surface of nano‐CaCO3 particles is treated with a silane coupling agent, namely, (3‐Glycidyloxypropyl) trimethoxysilane (GPTMS). Th...

Enhanced electrochemical and optical properties of poly(3-methylthiophene)/tungsten oxide (PMeT/WO3) hybrid nanostructure based electrochromic devices (ECDs) are presented. Hybrid nanostructures were prepared by electrodeposition technique in the presence of four different ionic liquids; 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF4), 1-bu...

In the present study, the electrosynthesis and the electrochemical characterization of azo dyes doped poly(3,4-ethylenedioxythiophene (PEDOT) were described. PEDOT film was electrochemically deposited onto indium doped tin oxide (ITO) coated/glass electrode, following azo dyes adsorption. The electropolymerized-PEDOT films on ITO glass were doped w...

This study focuses on the electrochromic device (ECD) applications of poly(3,4-ethylenedioxythiophene)/tungsten oxide (PEDOT/WO3) hybrid nanofibers prepared via electrospinning method. Nanoporous WO3 films were initially electrosynthesized on Pt sheet. The PEDOT layer was electropolymerized onto the entire surface of the WO3 nanoporous host framewo...

The tungsten oxide (WO3) nanofibers were grown directly onto an ITO-coated glass via an electrospinning method for electrochromic applications. The electrochromic properties of WO3 nanofibers were investigated in the presence of different electrolytes including a series of ionic liquids and classic LiClO4-PC system. A significant optical modulation...

We report the first successful applications of tungsten oxide/conducting polymer hybrid nanofiber assemblies in electrochromic devices. Poly(3,4-ethylenedioxythiophene)/tungsten oxide (PEDOT/WO3) and polypyrrole/tungsten oxide (PPy/WO3) composites were prepared by an in situ chemical oxidative polymerization of monomers in different ionic liquids;...

Much effort is currently devoted to implementing new materials in electrodes that will be used in electrochromic (EC) technology. Tungsten oxide (WO3) has emerged as one of the key materials for EC devices (ECDs) since it shows the best EC activity among transition metal oxides. However, hybrid nanostructures have been investigated in order to enha...

Poly(3,4-ethylenedioxythiophene)/tungsten (PEDOT/W) composites were prepared by an in situ chemical oxidative polymerization of 3,4-ethylenedioxythiophene in different ionic liquids; 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF4), 1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF6), 1-butyl- 3-methylimidazolium bis(trifluoromethylsul...

A facile approach of polypyrrole (PPy)/tungsten oxide (WO3) composites electrosynthesized in ionic liquids for fabrication of electrochromic devices is discussed. The electrochromic properties of PPy/tungsten oxide nanocomposite films (PPy/WO3) prepared in the presence of four different ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate (...

A rational strategy for fabricating PEDOT-S/PVA (poly(4-(2,3-dihydrothieno [3,4-b] [1,4] — dioxin-2-yl-methoxy)-1-butanesulfonic acid/polyvinyl alcohol) nanofibers by in situ-plasma deposition was developed.
