Abstract

The electrochemical doping-undoping process in conductive polymers: polyacetylene, polypyrrole, and polyaniline was investigated by means of the FFT impedance method, when the polymers were used as cathode. The impedance-frequency dispersions for the anion doping-undoping process of the polymer films were basically interpreted by the equivalent circuit shown. The conditions of ion-doped films were strongly correlated to the resistive component, Rr, in the equivalent circuit, and the doping-undoping process could be readily checked by the Rr component. Accordingly, the FFT impedance method can become a powerful tool for the studies of the doping-undoping process in conductive polymers.
