Polypyrrole (PPy) films were studied by ac impedance spectroscopy both in a free-standing membrane and in a modified electrode arrangement. The experimental results were analyzed by comparison with previously derived kinetic models, allowing to obtain, through a non-linear least-squares fitting proc
## Abstnwt-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 p
