The effect of thermal treatment on the structure and electrical/optical properties vapor phase-polymerized poly(3,4-ethylenedioxythiophene):tosylate (PEDOT:Tos) polypyrrole:tosylate (PPy:Tos) polymer films was investigated. Thermal applied postpolymerization but prior to washing embedded oxidant layer out film. Structural chemical changes arising from were studied in context their conductive electrochromic behavior. Spectroscopic analysis indicated a rise doping levels both polymers when...
Vapor phase polymerization (VPP) is used to fabricate a series of tosylate-doped poly(3,4-ethylenedioxythiophene) (PEDOT) electrodes on carbon paper. The VPP PEDOT/tosylate coatings has varying levels crystallinity and electrical conductivity because the use (or not) nonionic triblock copolymers in oxidant solution during synthesis. As result, impact structure charge storage capacity investigated using tetra-n-butylammonium hexafluorophosphate (0.1 M acetonitrile). ability insert anions,...
Pyridinium triflates are highly dissociated protic ionic liquids, and nonstoichiometric compositions have been used in energy devices such as the all-organic proton battery. Herein, we use a combination of pulsed field gradient NMR spectroscopy electrochemical impedance to investigate charge transport properties liquid 2-fluoropyridinium triflate variation with acid-doping level. While all diffusion coefficients decreased level acid doping, room-temperature conductivity increased because...
Conducting polymers are widely researched in terms of both their electrical and optical properties.These properties typically observed on the macroscopic (mm 2cm 2 ) scale using techniques such as UV-Vis-NIR spectroscopy.To broaden application, fabrication characterization conducting microscale (µm required.In this paper, poly(3,4-ethylenedioxytiophene)-tosylate (PEDOT:Tos) layers were vapor deposited at tip a single mode fiber.This was done without need for intermediate Indium Tin Oxide...
Vapor deposition of tosylate-doped poly(3,4-ethylenedioxythiophene) (PEDOT) has been templated to create hollow nanosphere coatings on carbon paper electrodes. The electrochemistry the PEDOT were characterized in nonvolatile and nonflammable Li-based N-methyl-N-propyl pyrrolidinium bis(fluorosulfonyl)imide electrolytes. These electrodes exhibit high electrochemical activity for given deposited mass owing their heightened active area. Furthermore, a multilayer nanospheres as cathode Li coin...

To broaden application, fabrication char- acterization conducting nanoscale thickness required. In this study microscale volume poly(3,4-ethylenedioxytiophene)-tosylate (PEDOT:Tos) layers fabricated at tip a single mode fibre without need for intermediate such as Indium Tin Oxide. This allows interrogation (primarily 1550 nm)...
