摘 要:
运用自行研制的常压低温等离子体设备对超高相对分子质量聚乙烯（UHMWPE）纤维进行了表面处理,选用正交试验法通过润湿性测试优化出不同工作气氛下的工艺条件,采用强力测试、扫描电镜（SEM）和光电子能谱仪（XPS）分析了等离子体处理前后UHMWPE纤维的性能变化。结果表明,常压低温等离子体在Ar携带丙烯酸和Ar／O2的气氛下处理UHMWPE纤维,表面改性效果良好。特别是选用Ar／O2流量比100：1,处理速度为5．8 m／min,输出功率189 W,可满足连续化生产。[著者文摘]

Abstract:
The surface modification of ultrahigh-molecular weight polyethylene （UHMWPE） fiber was conducted with a self-developed normal-pressure low-temperature Plasma apparatus. The optimal process conditions were decided under different atmosphere by orthogonal experiment and wettability test. The change of the properties of UHMWPE fiber was analyzed before and after plasma surface treatment by strength test, scanning electron microscopy （SEM） and X-ray photon spectroscopy （XPS）： The results showed that the normal-pressure low-temperature plasma yielded fairly good surface modification result under argon-and-acrylic acid atmosphere and Ar/O2 atmosphere. The continuous production can be realized under the conditions of Ar/O2 flow ratio 100 ： 1, treating rate 5.8 m/min and output power 189 W.[著者文摘]
