摘　　要：在空气环境下用等离子体对芳砜纶(PSA)纤维进行表面改性,研究纤维改性前后断裂强度、摩擦性能和润湿性能的变化。用场发射扫描电子显微镜(FESEM)和X射线光电子能谱仪(XPS)分析纤维表面的形貌和化学元素变化。结果表明:芳砜纶纤维经等离子体改性后,纤维摩擦性能和润湿性能明显提高;纤维的断裂强度无明显变化;纤维表面碳元素含量明显下降,同比下降11.15%,氧和氮元素含量明显增加,同比分别上升49.14%和15.95%,纤维表面极性基团增加。综合考虑实验的最佳工艺参数为40Pa、100 W、2min。The surface of polysulfonamide（PSA）fiber was modified by air plasma.The breaking strength,friction performance,and wettability of fiber before and after surface modification were investigated.The surface morphology and chemical composition of fiber were evaluated by Field Emission Scanning Electron Microscopy（FESEM）and X-ray Photoelectron Spectrometer（XPS）.The result showed that after plasma treatment,the friction performance and wettability were greatly improved.The breaking strength of PSA fiber was changed less.The carbon element was decreased by 11.15%,the oxygen element and nitrogen element were increased by 49.14%and 15.95%respectively,and polar groups on PSA fiber surface were increased.The optimum processing parameters were 40 Pa pressure,100 W power,and 2min treatment duration.
