N2 - Comparative studies of the anodic oxidation of N-phenyl-p-phenylenediamine (NPPD) on a bare Pt electrode, as well as Pt coated with poly(3-methylthiophene) (P3MT) and poly(thiophene) (PT) films, reveal the peculiar role of free charge carriers inside the polymer bulk in determining the kinetics of the electron-transfer reactions at the polymer/solution interface. The 'memory' effect in conducting polymers, which is usually attributed to various non-equilibrium processes in the course of their electrochemical doping, manifests itself clearly on the cyclic voltammetric curves.
