Abstract

Electroactivity with continuous cycling and the electrochemical behaviour of polyfuran perchlorate films (PFu/ClO4) were investigated to determine the reversibility of doping/dedoping processes and the electrochemical mechanism of these processes as a function of the electropolymerization potential. A surface capacitive oxidation mechanism and a diffusion controlled mechanism in the dedoping process were detected when the potential scan rate was varied in D′ films (ηp = 2.3 V). Moreover, D films (ηp = 2.1 V ) showed a mixture of mechanism in the reduction processes. The polymeric material was found to deteriorate with continuous charge–discharge over successive days.
