聚合物材料的离子束表面改性及工程应用前景

Ion beam induced surface modification of polymer and application for engineering

介绍了运用高能离子束对聚合物材料进行表面改性的新工艺。聚合物材料经高能离子注入后其电导率、表面硬度、耐磨性等性能都得到了提高。特别是其表面硬度远高于目前公认的最硬的马氏体钢，其耐磨性明显优于滚珠轴承钢。通过比较几种不同类型的聚合物材料在注入前后表面硬度的变化，分析注入离子种类、注入能量、注入剂量等工艺参数对聚合物的影响。利用交联网状结构模型分析聚合物强化机理，比较好地解释了上述性能改善的原因。并对这种新工艺的工程应用前景进行了探讨。

Ion beam induced surface modification of polymer was extensively discussed. Ion beam processing improved on chemical and physical properties such as conductivity, surface hardness and wear resistance. Especially the polymer by ion beam processing exceeds martensite steel in the surface hardness. The surface hardness variations of some kinds of polymers were compared and the influence factors such as ion species, particle energy and dose were analyzed. Among the researches of bombarded polymers, the cross linked structure efficiently account for these improvements of physical characters. Besides, the application for the engineering was studied.
