Title: Method of coating a substrate in carbon dioxide with a carbon-dioxide insoluble material

Abstract: A method of treating a substrate comprises contacting a surface of said substrate, with a pressurized fluid comprising carbon dioxide and a surface treatment component, the surface treatment component being entrained in the pressurized fluid and contacting the surface so that the surface treatment component lowers the surface tension of the surface of the substrate and treats the substrate. The contacting step is preferably carried out by immersion, the fluid is preferably a liquid or supercritical fluid, the substrate is preferably a metal or fabric substrate, and the surface treatment component is preferably a fluoroacrylate polymer.
