ECTFE surfaces modified by fluoro-oxidation and a process therefor

摘要

A process for fluoro-oxidation of the surface(s) of an ECTFE substrate, film or three-dimensional object, and the surface-modified substrate, film or object produced thereby. The process includes exposing the surface(s) to concentrations of fluorine and oxygen for a time sufficient to increase the surface energy and thereby lower the surface contact angle sufficiently to permit bonding. The surface modification allows bonding to an adhesive with the adhesive being bondable to a plastic or metal substrate.
