Abstract
A composite polymeric material having metallic surface properties is prepared by subliming solid crystalline polymeric sulfur nitride to a vapor, and thereafter condensing the polymeric sulfur nitride vapor onto the surface of a highly-oriented thermoplastic polymeric substrate to thereby form on the substrate an epitaxial crystalline polymeric sulfur nitride film. The polymeric sulfur nitride film is completely oriented parallel to the direction of orientation of the substrate and has a relatively high degree of anisotropy with respect to its electrical conductivity and optical properties.
