CONDUCTIVE BILAYER POLYMER-FILMS FORMED BY POLYANILINE AND POLYMERIC IONIC CONDUCTOR

Conductive bilayer polymer films based on polymer electrolyte and poly aniline have been prepared by the electrochemical polymerization of an iline on an electrode covered with an ionic conductive polymer film. E lectrochemical polymerization was carried out by the potentiodynamic m ethod. The electrochemical properties of the bilayer films were invest igated by cyclic voltammetry. The cyclic voltammograms indicated that the bilayer films have good redox stability, as well as reversibility, and show electrochemical activity in the solid state at room temperat ure. An all-solid-state rechargeable battery composed of lithium and t his bilayer polymer film was tested. The preliminary experimental resu lts showed that the battery can discharge in moderate electric current . (C) 1997 John Wiley & Sons, Inc.
