中文摘要：

将不同质量分数的氟硅与甲基丙烯酸甲酯嵌段共聚物（PMTFPS-b-PMMA）和甲基丙烯酸甲酯（PMMA）配制成2.00wt%溶液,经旋涂、退火处理后得到共混聚合物膜。以水、二碘甲烷和甲酰胺为参比液,利用接触角测试仪测定了共混聚合物膜的表面能。研究结果表明：当共混聚合物中PMTFPS链段含量在由0.28wt%增大至5.67wt%时,表面能从26.90mN/m降到14.49mN/m,共混物涂膜表面氟元素的相对含量从0.93%急剧增加到14.27%;随PMTFPS链段含量的进一步增加,共混物膜表面能仅略有下降,表面氟含量增加也不明显,说明此时共混物膜的表面组成已趋于稳定。

英文摘要：

Polymer blend films of PMTFPS-b-PMMA block copolymers and PMMA homopolymer with different mass fractions were prepared by means of spin-casting with 2.00 wt% solution and annealing treatment.The surface energy of the polymer blend film was measured by contact angle meter with water,diiodomethane and formamide as the reference liguids.The research results show that,as the PMTFPS chain segment content increases from 0.28 wt% to 5.67 wt%,the surface energy of the polymer blend reduces from 26.90 mN/m to 14.49 mN/m,and the relative content of fluorine in the polymer blend membrane sharply increases from 0.93%to 14.27%;with the further increase of PMTFPS chain segment content,the surface energy of the polymer blend only reduces slightly,and the increase of surface fluorine content is also not obvious,indicating that the surface composition of the polymer blend membrane is tending to be stable under such conditions.
