18. Ozone will remove ambient organics and perfluoropolyethers from a surface and thereby increase the surface hydrophilicity. When a surface is first irradiated with far-UV light and then lubricated in the laboratory with a perfluoropolyether, there is no measurable increase in adhesion or water contact angle over that measured for an unirradiated surface.
