SIMPLE-MODEL FOR ELUCIDATION OF NATURE OF CURRENT-GENERATING PROCESSES IN POLYANILINE-TYPE CONDUCTIVE POLYMERS

According to suggested simple model in the practically important poten tial range (E approximate to 0 ...+ 0.6 V against SHE) the nature of t he electrochemical current-generating processes in conductive polymers of polyaniline type is not associated with a particular redox reactio n, but it reduces to the charge/discharge of the double electric layer capacity, which is anomalously high (300 ... 850 F/g) in such systems due to structural peculiarities of these materials. The model gives a good fit to electrode behavior in this range.
