Process for making thin polymer film by pulsed laser evaporation

摘要

A process for producing thin film of a first addition polymer on a substrate comprising bombarding a target, consisting essentially of a second addition polymer, with radiation from a pulsed laser in a vacuum or gas atmosphere to form a plume of components of said second polymer; and depositing said plume on a substrate, whereby a film of said first polymer is formed. The first and second addition polymer may be identical or different and in both cases may be fluoropolymer.
