摘　　要：通过等离子体处理在超高分子量聚乙烯(UPE)表面接枝极性基团,增强其与环氧树脂(EP)基体的界面粘附力,改性UPE的加入增强了环氧树脂EP的自润滑性能。结果表明:添加质量分数4%的改性UPE,使EP复合材料的摩擦系数和比磨损率降低至0.016和0.98×10^(-5)mm^(3)/(N·m),相比于纯EP,分别降低了96.3%和91.1%。In this work,polar groups were grafted on the surface of ultra-high molecular weight polyethylene(UPE)by plasma treatment to enhance its interfacial adhesion with epoxy resin(EP)matrix,and the incorporation of modified UPE enhanced the self-lubricating properties of epoxy EP.The results showed that the addition of 4wt.%of modified UPE reduced the coefficient of friction and specific wear rate of EP composites to 0.016 and 0.98×10^(-5)mm^(3)/(N·m),respectively,which were decreased by 96.3%and 91.1%compared with pure EP.
