摘　　要：通过自由基聚合将γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH570)分别与甲基丙烯酸甲酯MMA、甲基丙烯酸丁酯BMA、苯乙烯St进行共聚。采用旋涂法将所得聚合物涂覆于聚对苯二甲酸乙二醇酯(PET)薄膜表面。研究不同含量的硅烷偶联剂、引发剂、不同种类单体对PET薄膜表面性能的影响。数据表明,相比于PET薄膜,涂覆有共聚物的PET薄膜性能有较大变化,透光率有一定程度增大,表面自由能有所减小。Methacryloxy propyl trimethoxyl silane（KH570）and methyl methacrylate（MMA）or butyl methacrylate（BMA）or styrene（St）had been polymerized respectively by radical polymerization.These kinds of copolymers were coated on the surface of polyethylene terephthalate（PET）films by spin coating.The influence of contents of KH570 and initiator,and different of monomers on the surface properties of PET film had been studied.The data indicated that the surface properties of PET film were improved greatly by coated copolymer.The light transmittance was increased but surface tension decreased when comparing with that of natural PET film.
