Perfluoroalkyl ethyl acrylate(FA) copolymers were prepared by solvent polymerization using FA mixture, stearylmethacrylate and vinylidene chloroide as comonomers. A film of FA copolymer was formed on a slide glass, and its surface properties were analyzed by measuring the contact angles with DCAA(Dynamic contact Angle Analyzer). the solid content of FA copolymer in the copolymer cating solution used to prepare the film of FA copolymer should be above 0.08wt%. The oil repellency of FA copolymer is more dependent upon the FA content of FA copolymer than the water repellency. The critical surface tension of FA copolymers varies sensitively with FA content. The critical surface tension of FA copolymers, whose FA content is in the range of 40-60wt%, shows a value between 18.0 and 8.2 dyne/cm. Young-Fowkes equation and Young-Kaelble equation are suitable for the prediction of surface energy of FA copolymer. The surface energy of FA copolymers consists of mainly dispersion component.
