研究了通过自由基链转移反应原位接枝聚合物膜。所得聚合物膜经红外(FT- IR)、X射线光电子能谱(XPS)、原子力显微镜(AFM)、接触角及椭圆偏光测量 进行了表征。两种单体如苯乙烯/甲基丙烯酸甲酯共聚合时,改变单体对的组成, 可以得到不同亲水亲油性质的表面。

Surface chain transfer reaction was used to prepare end-grafted polymer films of nanometer dimensions. Homogeneous polymer film of more than 25 nm thick was obtained after polymerization of MMA for above 24 h. Copolymerization of acrylic acid/styrene and acrylonitrile/methyl methacrylate with different molar ratios could result in polymer-modified surfaces with different physical properties.

Key words: STYRENE, METHYLMETHACRYLATE, COPOLYMERIZATION, CHAIN TRANSFER, XRD, AFM
