Electron beam functionalised hydrophilic polymer coated membrane

A membrane includes a base membrane, formed from a polymer such as polyvinylidene difluoride, poly(tetrafluoroethylene-cohexafluoropropylene), poly(ethylene-alt-tetrafluoroethylene), polychlorotrifluoroethylene, poly(tetrafluoro-ethylene-co-perfluoropropyl vinyl ether), poly(vinylidene fluoride-co-hexafluoropropylene), polyvinyl fluoride, polytetrafluoroethylene; and an electron beam functionalized hydrophilic coating. The hydrophilic coating is a polymer having an average molecular of greater than 2500 Daltons selected from polyvinyl alcohol, a polyvinyl alcohol-polyvinyl amine copolymer, a polyvinyl amine, polyacrylic acid, polyacrylates, polyethylene glycol, polyethylene amine, and derivatives thereof functionalized with an electron beam reactive group adapted to form a radical under high energy irradiation. Also disclosed are processes for forming the membrane.
