Surface-initiated atom transfer radical polymerization (ATRP) of <I>tert</I>-butyl acrylate was carried out directly from a nonmodified poly(vinylidene fluoride-<I>co</I>-trifluoroethylene) [P(VDF-<I>co</I>-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-<I>co</I>-TrFE) film without any change in the bulk physical properties. Also the effect of surface nanotexture formation on wettability was investigated.
