摘　　要：以γ-甲基丙烯酰氧丙基甲氧基三(三甲硅氧基)硅烷和甲基丙烯酸甲酯为原料制备不同硅含量的含硅共聚物。测试了共聚物的Tg、表面接触角、表面自由能,同时对共聚物进行FTIR和表面电子能谱(XPS)分析。结果表明,随着共聚物中硅单体含量的增加,其表面能显著降低,且共聚物在成膜过程中,含硅基团有向共聚物-空气界面富集的趋势。Different silicon content copolymers of y-methacryloxypropyl tris（trimethylsiloxy）silane were prepared. The glass-transition temperature, contact angles and surface free energy of the copolymers were tested. IR and XPS were used to detect the surface of the copolymers. When the silicon content of the copolymer increased the surface free energy of the copolymers significantly reduced. During the film-formation of these copolymer, the silicon containing groups enriched to the air interface.
