Abstract

Metal bondable surfaces of films of paraxylylene polymers are provided by immersing the films in a solution of concentrated sulfuric acid containing about 1% by weight of AgNO(3) at elevated temperatures for a time period of about 30 to about 60 minutes. The films are then immersed in a 20% methylene chloride epoxy solution to form a thin epoxy coating on surface of the film. The film and its coating are further treated with calcium carbonate to make it receptive to an electrolessly deposited metal.
