摘要：

We discuss in detail the equivalent circuits used to model the impedance of electronically conducting polymer systems and the procedure for the impedance analysis of these systems to account for deviation from the ideal behaviour. Impedance spectra of pyrrole-based and thiophene-based polymers of different thickness and at different values of injected charge in cells with liquid electrolytes and solid polymer electrolytes are reported, and the electrochemical parameters are evaluated and discussed.
