It was electrocoated on carbon fiber microelectrode (CFME) as an active electrode material in 0.1 M sodium perchlorate (NaClO4)/acetonitrile (ACN) solution. The electropolymerization process was successfully performed less amount of 3 mM. The characterization of Poly(BzCz)/CFME thin films was performed by Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR) and Electrochemical impedance spectroscopy (EIS). The effects of monomer concentrations (1, 2, and 3 mM) during the preparation of modified electrodes were examined by EIS. Capacitive behaviors of modified CFMEs were defined via Nyquist, Bode-magnitude and Bode-phase plots. Variation of capacitance values by initial monomer concentration and specific capacitance values are presented. The highest specific capacitance value for a potensiodynamically prepared polymer thin film in the initial monomer concentration of 1 mM with a charge of 4.54 mC cm(-2) was obtained about 221.4 mu F cm(-2). An equivalent circuit model, R(C(R(QR)))(CR), for different concentrations of Poly(BzCz). CFME was proposed and experimental data were simulated to obtain the numerical values of circuit components.en10.1007/s12221-011-0296-9info:eu-repo/semantics/closedAccess9-benzyl-9H-carbazoleCarbon fiberElectrochemical impedance spectroscopyEquivalent circuitConducting polymerElectrochemical Impedance SpectroscopyPolycarbazole Thin-FilmsConducting PolymersCarbazolePolymerizationElectropolymerizationPoly(N-Methylaniline)DerivativesOxidationDopamineArticle123296302Q2WOS:0002907395000022-s2.0-79958027085Q2
