Corrosion resistant metal laminates having, in series, a metal layer, a non-metal conductive layer and a non-conducting layer. The non-metal conductive layer comprises inherently conducting polymer, e.g. polyaniline or polypyrrole, in a non-conducting matrix, e.g. an inorganic matrix such as a silicate, a thermoplastic polymer matrix such as a polyolefin or a vinyl polymer or a thermoset polymer matrix such an epoxy, a polyurethane or a polyimide. Preferred intrinsically conductive polymers include sulfonic acid doped polyaniline. The inherently conducting polymer-containing matrix is preferably strongly adhesive to metal and provides enhanced corrosion resistance to the metal in a variety of corrosive environments such as acidic, alkaline, and salt environments. |
