✦ Synopsis

The electrochemical behavior of poly(N-methylpyrrole) (PNMP) has been studied in aqueous solution by cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM). The electrochemical process of P N M P (TsO-) in TsONa solution or PNMP(N0,) in NaNO, solution showed good chemical reversibility. The process only involved the anion doping and dedoping. PNMP(Ts0-) kept good electrochemical activity in NaNO, or Na2S04 solution. But PNMP(N0,) became less active electrochemically in Na2S04 solution and inactive in TsONa solution. PNMP(N0,) in NaCl solution showed similar electrochemical behavior to that in NiClp solution.

The reduction of H+ cations on the Pt electrode coated with poly(N-methylpyrrole) (PNMP) film was studied in an acidic aqueous solution. The reduction depends strongly on the counteranions originally doped in PNMP during polymerization. H+ cations can penetrate the neutral or overoxidized film from
