ABSTRACT:
Electrical devices which comprise at least one metal electrode and a conductive polymer element in contact therewith, wherein the metal surface which contacts the conductive polymer has a roughened or otherwise treated surface to improve its adhesion to the conductive polymer. The metal electrode is preferably an electrodeposited foil. The conductive polymer preferably exhibits PTC behavior. The devices include heaters and circuit protection devices. The improved adhesion results in improved physical and electrical stability, and broadens the range of conductive polymer compositions which can be used in a number of important applications.
