Poly(3HTh)/CFME is characterized by Cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR), Scanning electron microscopy-Energy Dispersive X-ray analysis (SEM-EDX), and electrochemical impedance spectroscopy (EIS). The effects of different monomer concentrations (0.5, 1.0 and 1.5mM) on polymer were reported in 0.1M tetraethyl ammonium tetrafluoroborate (TEABF4)/acetonitrile (ACN) solution. The highest low frequency capacitance (C-LF = 1.394 mF cm(-2)) was obtained for [3HTh](0) = 0.5mM. The equivalent circuit model of R(QR(CR)(RW))(CR) was examined for polymer/electrolyte system.en10.1080/03602559.2012.699132info:eu-repo/semantics/closedAccess3-HexylthiopheneCarbon fiberCircuit modelCoatingsMicro-capacitorThin filmsElectrochemical Impedance SpectroscopyCarbon-Fiber MicroelectrodesLight-Emitting-DiodesConducting PolymerFilm ElectrodesSolvent TransportN-MethylpyrroleThin-FilmsPolythiophenePolyanilineMicro-Capacitor Behavior of Poly(3-Hexyl Thiophene)/Carbon Fiber/Electrolyte System and Equivalent Circuit ModelArticle511212581265Q2WOS:0003080262000142-s2.0-84865526173N/A
