Abstract 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 PNMP (TsO ‐ ) in TsONa solution or PNMP(NO 3 ‐ ) in NaNO 3 solution showed good chemical reversibility. The process only involved the anion doping and dedoping. PNMP(TsO ‐ ) kept good electrochemical activity in NaNO 3 or Na 2 SO 4 solution. But PNMP(NO 3 ‐ ) became less active electrochemically in Na 2 SO 4 solution and inactive in TsONa solution. PNMP(NO 3 ‐ ) in NaCl solution showed similar electrochemical behavior to that in NiCl 2 solution. © 1996 John Wiley & Sons, Inc.
