When PAN is synthesized by cyclic voltammetry, the redox peak current and voltage will inevitably increase, because polyaniline is a highly conductive polymer. At the beginning of the first cycle, less polyaniline is produced, which has two States, complete state PAN and intermediate oxidation state PAN with three peaks (including phenylenediamine and quinonediimine). With the increase of turns, the charge Q deposited on the cathode increases, and the current naturally increases, regardless of the conductivity. If you want to say that the conductivity increases, it will also increase. Under the autocatalytic action of PAN, with the increase of PAN dosage and polymerization speed, the corresponding current will naturally increase. Otherwise, the synthesis needs will not be met and the reaction will stop. I'm not a major, so I may not be clear. I suggest reading related papers: Wu Kezhong et al., Electrochemical Synthesis of Polyaniline by Cyclic Voltammetry.
