Abstract:
A process for the application of a metal film on a polymer surface comprising the steps of:(a) enrichment of Lewis acids or Lewis bases on said polymer surface by means of a vacuum plasma treatment, said vacuum plasma treatment comprising a plasma gas adapted to said polymer; (b) nucleation under vacuum with a catalytically active platinum metal and/or platinum metal compound by means of a second plasma treatment, said second plasma treatment comprising a second plasma gas containing an evaporated form of said platinum metal and/or platinum metal compound for nucleophilic and/or electrophilic reaction on said Lewis acids or said Lewis bases; (c) autocatalytic precipitation of a coating of a metal from an aqueous solution without any external current supply; and (d) electrolytically applying at least another coating of metal, wherein said plasma gas used for the enrichment of said Lewis acids or said Lewis bases on said polymer surface contains a halogen or a hydrohalogen.
