摘　　要：采用Ｏ３－ＵＶ处理硅橡胶膜，在其表面形成过氧化物基团，然后用接枝聚合方法在表面上接枝丙烯酰胺。对接枝改性后的材料进行接触角、摩擦系数等测定，用扫描电镜观察表面形貌。结果表明。O3-UV pretreated onto silicone to form peroxidates on the silicon surface, surface graft polymerization of acrylamide was carried out on these silicone films, which maked these films achievement of surface lubricity .The water contact angle and maximum motionless friction(μmax) of surface-modification silicone films was greatly reduced. SEM micrographs showed that surface-structure of PAAm-grafted silicone films was different from that of virgin silicone films.
