ABSTRACT:
A method for electroless plating relatively inert plastics, e.g., polyvinylidene fluoride, with metal, such as gold, copper or nickel has been developed. The process requires that the plastic be treated with a solvent such as n,n-dimethylformamide or dimethylsulfoxide. The plastic is then sensitized with silver followed by treatment with a suitable activator for the electroless plated solution. Continuous adherent thin films of the desired metal coating are produced.
