摘　　要：采用自由基溶液聚合法合成界面改性剂丙烯酸十二烷基酯、苯乙烯和3-甲基丙烯酰氧基三甲氧基硅烷的三元共聚物(St/LA/KH-570),对进行氧化处理后的碳纤维进行表面改性。通过红外光谱、核磁谱图和凝胶渗透色谱对界面改性剂进行表征。结果表明:合成的界面改性剂能很好的涂覆于碳纤维表面,碳纤维增强聚丙烯复合材料的界面粘结也得到改善,且复合材料的力学性能有所提高。A interfacial modifier of acrylate, dodecyl acrylate, styrene and 3-methacryloxy propyl trimethoxy silane terpolymer （St/1A/KH570） was synthesized by free radical solution polymerization,applied in the oxidation treatment of carbon fiber surface modification. By IR, 1HNMR spectrum, gel permeation chromatography to characterize the interracial modifier. The results showed that the interracial modifier can be well applied to the surface of carbon fiber,carbon fiber reinforced polypropylene composite bonding interface was also improved,and the mechanical properties of the composites increased.
