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 one which binds to 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.
