The results presented in this paper reveal that the electrochemical degradation of polyaniline is strongly dependent on the potential window. Substantial agreement is observed between calculated and experimentally obtained values for the electrochemical parameters of films, i.e. peak current and charge. These results also reveal that the efficiency of the cyclic redox process is well below 100%.
