中文摘要：

聚合物表面改性方法多种多样，结合聚乙烯、聚苯乙烯、聚碳酸酯、聚甲基丙烯酸甲酯这些具体材料详细介绍目前应用广泛的溶液处理法、低温等离子体处理法、表面接枝法、离子注入法和一种新兴的原子力显微探针震荡法。前几种方法都是化学处理法，在基底上形成的新的极性表面层与体相结合一体，非常牢固；最后一种方法为物理过程，能够精确控制改性区域，对于改善材料表面微摩擦性能有重要作用。

英文摘要：

There are many methods for the surface modification of polymer. As for PE, PS, PC and PMMA, there are solution disposing, low temperature plasma disposing, surface grafting, ion implantation and a novel method of the scratching with tip oscillation of an AFM. The former ones are involved in chemical reactions and result in a new polar surface that is firmly combined to the bulk material; the last one is just a simple physical proeess, but the areas to be modified could be well controlled, which may be very important to the improvement of the surface micro-lubrication.
