HYDROPHILIC EXPANDED FLUOROPOLYMER MEMBRANE COMPOSITE AND METHOD OF MAKING SAME

摘要

A hydrophilic expanded fluoropolymer membrane having a coating comprising a copolymer comprising a non-wetting monomer and a fluoromonomer is described. In one embodiment, the non-wetting monomer and fluoromonomer are cross linked. A process of vaporizing, condensing and curing a formulation or formulations comprising the non-wetting monomer and/or the fluoromonomer is described. In one embodiment the condensed formulation is exposed to a high energy source such as a UV lamp for example to cross link the non-wetting monomer with the fluoromonomer. The coating may be conformable coating and may provide a hydrophilic membrane that has high water flow rates.
