摘　　要：以甲基丙烯酸丁酯、苯乙烯、丙烯酸丁酯、2-羟基丙烯酸丙酯和全氟丙烯酸酯为原料,通过自由基聚合,制备了含氟丙烯酸共聚物。利用接触角分析仪、差示扫描量热分析(DSC)、扫描电子显微镜和X射线能谱分析对含氟烷基链长及含量对涂膜表面性能的影响进行了研究。结果表明,在含氟丙烯酸酯类单体的含量一定的情况下,涂膜与水的接触角随着全氟烷基链长度的增加而增加;另一方面,在含氟单体的含量小于3%(质量分数,以下同)时,接触角随着单体含量的增加而增加;当含氟单体的含量超过3%时,继续增加含氟单体的用量对接触角的影响不大。Fluoro-contained acrylate copolymers are synthesized by free radical polymerization of butyl methacrylate, styrene, butyl acrylate, 2- hydroxyl propylacrylate and perfluoroacrylate. The influences of the side chain length and amount of fluoro- contained alkyl to the surface properties of the coating films are studied by contact angle analyzer, DSC, SEM and EDAX （energy dispersive analysis of X - Ray）. The results show that the longer the chain length of perfluoroalkyl is, the bigger the contact angle between coating film and water becomes at a given content of fluorinated monomers. In addition, the contact angle accrues with the amount of the fluorinated monomers if its amount is below 3% ; while the contact angle doesn＇t change much if the amount of the fluorinated monomers is higher than 3%.
