| According to suggested simple model in the practically important potential range (E ≈ 0... + 0.6 V against SHE) the nature of the electrochemical current-generating processes in conductive polymers of polyaniline type is not associated with a particular redox reaction, 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. |
