Poly(o-aminophenol) (POAP) films weredeactivated and then reactivated, and dependences of the different charge-transportand charge-transfer parameters on the degree of deactivation (qc) were obtained by employingElectrochemical Impedance Spectroscopy. While some parameters, such asinterfacial metal-film and film-solution resistances the high-frequencycapacitance and the redox capacitance exhibit a continuous variation withouthysteresis between deactivation and reactivation processes within the whole qc range, others, such as electron andion diffusion coefficients show not only marked changes of slope from given qc values but also hysteresis betweenconsecutive deactivation and reactivation processes.
