摘　　要：本文简要介绍了几种高性能有机纤维(芳纶、PBO、UHMWPE、PPS等)的性能及其应用,并阐述了低温等离子体技术对这些纤维表面性能的改性研究情况,发现等离子体处理可以对纤维表面产生物理刻蚀和化学改性作用,不仅能显著增加纤维的表面粗糙度,还能在纤维表面引入一些极性基团,降低纤维的表面能,从而提高了纤维与树脂基体的粘结性能;同时,等离子体技术操作简单,对环境污染少,因而是一种很有效的环境友好型改性技术,很适合运用在高性能有机纤维表面改性领域。This article simply introduces the properties and applications of several high performance organic fibers and describes studies on the surface modification of these fibers by using the low - temperature plasma technology. It＇ s shown that plasma treatment well modifies the properties of fiber surface by physical etching and chemical modification. It can not only roughen the surface of the fibers, but also implant some active polar groups on the fiber surface, reducing the surface energy, both causing the enhancement of the adhesion between the fibers and the polymer matrix; Meanwhile, it is a simple process without any pollution, so it＇s an effective and environmentally friendly way to modify fiber surfaces, especially to the high performance organic fibers.
