ABSTRACT:
A method for electroless deposition of metal onto a nonconductive surface of a substrate is disclosed. According to the method, the surface is contacted with a nonaqueous carrier polymer mixture comprising (a) an organic solvent, (b) a catalytic compound that is soluble in the solvent and contains a catalytic metal, and (c) a polymer or polymeric precursor that is soluble in the solvent and that can be formed into a polymeric film that retains its integrity at 200.degree. C. Excess solvent is removed from the surface to form a catalytic carrier polymer coating on the surface, the coating comprising catalytic compound adhered to a layer of carrier polymer adhered to the surface. The coating is activated to produce an activated catalytic carrier polymer coating on the surface, which is then contacted with an aqueous electroless plating mixture thereby to form a plated substrate having a film of metal over and adhered to the layer of carrier polymer. Various articles prepared by such method, and articles formed from fibers prepared by such method are also disclosed.
