Preparation of Poly(vinylidene fluoride-co-trifluoroethylene) Film with a Hydrophilic Surface by Direct Surface-initiated Atom Transfer Radical Polymerization without Pretreatment
Surface-initiated atom transfer radical polymerization (ATRP) of tert-butyl acrylate was carried out directly from a nonmodified poly(vinylidene fluoride-co-trifluoroethylene) [P(VDF-co-TrFE)] film surface to give a polymer brush, which was further converted to a poly(acrylic acid sodium salt) brush by hydrolysis. A hydrophilic surface was successfully created at the outermost Surface of P(VDF-co-TrFE) film without any change in the bulk physical properties. Also the effect of surface nanotexture formation on wettability was investigated.
