Conductive and semiconductive materials are coated with 0.1-100-μm polymer anticorrosive films by (1) grafting diazonium salts having groups that function as polymn. initiators onto the surface and (2) radical or ring-opening polymn. of the monomers on the surface. Thus, an Fe electrode was electrolytically grafted with p-BrCHMeC6H4N2BF4, and Me methacrylate was polymd. by ATRP on the grafted surface.
