Özet
9H-Carbazole-9-carbothioic dithioperoxyanhydride (2CS(2)Cz) was chemically synthesized in our previous study. In this work, specific (C-sp) and double layer capacitances (C-dl) of the electrocoated poly(9H-carbazole-9-carbothioic dithioperoxyanhydride) P(2CS(2)Cz) films were obtained on glassy carbon electrode (GCE). The polymers were characterized by cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and electrochemical impedance spectroscopy (EIS). Polymer characterizations of FTIR-ATR, and SEM-EDX analysis were taken on carbon fiber microelectrodes (CFMEs). The initial monomer concentration of 2CS(2)Cz was taken as 0.25, 0.5, and 1.0mM in 0.1M sodium perchlorate (NaClO4)/acetonitrile (CH3CN). The capacitance behavior of P(2CS(2)Cz)/GCE is shown by Nyquist, Bode-magnitude, Bode-phase, and Admittance plots relationship. The low frequency capacitance (C-LF=0.52 mFcm(-2)) and double layer capacitance (C-dl=571 mu F) were obtained for [2CS(2)Cz](0)=0.25mM and 1mM, respectively. [GRAPHICS] .
