Non-equilibrium electrical behaviour of polymeric electrochemical junctions

Current oscillations were observed at constant applied voltage in electrochemical heterostructures, composed of conducting polymer, solid electrolyte and a charge accumulating system ( graphite electrode or capacitor). These oscillations were attributed to the periodic modulation of the conductivity in the active zone of conducting polymer ( polyaniline) due to ionic flow in the solid electrolyte ( polyethylene oxide with LiC1O(4)).
