摘　　要：采用空气低温等离子体处理高强聚乙烯纤维,测试处理前后纤维表面摩擦系数的变化,并采用电子扫描显微镜(SEM)和原子力显微镜(AFM)对纤维表面形貌进行观察分析。结果发现,空气低温等离子体处理的刻蚀作用会在纤维表面形成致密的"小坑群",使得纤维表面产生剥落、联结,造成纤维表面的粗糙程度有所增加,其处理后的纤维表面静、动摩擦系数有所提高。Through the high strength polyethylene fiber treated by air low temperature plasma, test the fiber surface friction coefficient before and after treatment, observe and analyze the fiber surface morphology by SEM and AFM. The results show that air low temperature plasma treatment cause etching on the fiber surface, forming a dense ＂small pit group＂, the fiber surface spalling, connecting, increasing the roughness of fiber surface; the static and dynamic friction coefficients of treated fiber surface have been greatly improved.
