According to Holze [135], the redox pair (iipa = 0.32 V and = 0.28 V) that can be seen in Fig. 4.12a is related to the copolymer, as neither PANI nor POAP show such voltammetric peaks. The brownish-blue color of the polymer film obtained at a concentration ratio of 1 10 also differs from that of the monopolymers. The color of the films formed at other concentration ratios was yellow. The synthesized poly(aniline-co-o-aminophenol) was found to be electroactive, even at pH 10, and its conductivity was decreased by three orders of magnitude compared to PANI.
