Capacitive properties of the electrochemically grown homopolymer, poly(TsCz) film on carbon fibre microelectrode (CFME), are characterised by cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). Different monomer concentrations (1, 3 and 10 mM) were used for electrodeposition in 0.1 M sodium perchlorate (NaClO4)/acetonitrile (ACN) solution. The capacitive behaviour of modified CFMEs was defined via Nyquist, Bode-magnitude and Bode-phase plots. An equivalent electrical circuit R(CR)(QR)(CR) for different concentrations of poly(TsCz)/CFME was proposed and experimental data were simulated to obtain the numerical values of the circuit components. The Nyquist plot for poly(TsCz) shows the highest specific capacitance (50.0 mF cm(-2)) at frequency of 0.01 Hz in the initial monomer concentration of 10 mM.en10.1007/s12221-011-0008-5info:eu-repo/semantics/closedAccess9-tosyl-9H-carbazoleCarbon fibre microelectrodeElectrochemical impedance spectroscopyEquivalent circuit modelScanning electron microscopyCarbon-Fiber MicroelectrodesPolycarbazole Thin-FilmsPolyanilineSurfaceElectrosynthesisPolymerizationElectrolyteCompositesDepositionCopolymerArticle121814Q2WOS:0002879031000022-s2.0-79952270676Q2
