In this study, the p-type PPy/ClO₄^- and polyanion-doped PPy/PVS^- polymer electrodes were prepared at various polymerization electric charges by incorporating electrolyte anions of different molecular weight during potential step polymerization. The surfaces of the prepared electrodes were inspected by SEM and their electrochemical properties were investigated with CV and ac impedance method. The results suggested that anion was mobile ion for PPy/ClO₄^- electrode and cation for PPy/PVS^- electrode during redox reaction. As polymerization electric charges increased, the charge transfer resistances were decreased and the electric double layer capacitances were increased in the both electrodes. The surface areas of both electrode increased as polymerization electric charges increased. Especially, the morphological exchanges of surface may be more important effect in the electric double layer capacitance for PPy/ClO₄^- electrode than for PPy/PVS^- electrode.
