Abstract
Laminates of metals and electrically conductive polymers are prepared by a process in which first a layer of an electrically conductive polymer is applied onto the surface of the metal by treating the monomers with an oxidizing agent, the metal coated in this manner is immersed in a solution which contains an anodically polymerizable monomer and a conductive salt, and the monomer is anodically polymerized so that it is deposited onto the coated metal.
Claims4
A process for the preparation of a laminate of an aluminum or copper containing metal layer and an electrically conductive polymer which comprises:
- applying a solution of the polymer-forming monomer and a conductive salt onto the surface of the metal;
- treating the solution of the polymer-forming monomer and conductive salt with an oxidizing agent for a time sufficient to form a polymer of the selected monomer on the metal layer surface, and
- immersing the polymer film coated metal as an anode into a solution containing an anodically polymerizable monomer and a conductive salt, and
- applying a current to the solution to anodically polymerize the monomer and form an additional polymer film on the coated metal layer.
