Abstract
A fluorinated resin having enhanced wettability to water prepared by roughening a surface of the fluorinated resin such that a central line roughness average (Ra) of the surface is increased to at least 0.1 &mgr;m, and then depositing thereon a thin hydrophilic film while maintaining the central line roughness average (Ra) of at least 0.1 &mgr;m, the thin hydrophilic film being formed from a hydrophilic substance having a contact angle of water of less that 90°, and the resulting fluorinated resin having up to 20° of contact angle of water. The fluorinated resins are able to maintain high hydrophilicity even after prolonged exposure to the atmosphere and can be used in various fields that require bio-compatibility and in permeable membranes or filters.
