Abstract
We present kinetics studies of the conductivity decay of PANI(CSA)(0.5) fil ms cast from m-cresol solutions obtained through accelerated ageing tests. In first approximation, the conductivity degradation in air can be treated as a pseudo-first order process in which the time constant follow an Arrhen ius law. The related activation energy is linked to the PANI quality. Agein g studies in different atmospheres and FTIR characterization of unaged and aged films underline the role of dedoping, oxidation, and chemical crosslin king processes.
