摘要: 聚烯烃类聚合物粘结与印染性能均较差,以往都是用氧化剂法改善其表面性能[1],近年来采用等离子体表面处理的方法,不仅能改变表面的润湿性,而且无污染、效率高[2~4],完全有可能取代传统的表面处理方法。

Abstract: The surface of polytetrafluoroethene (PTFE) was treated by air plasma in the equipment designed by ourselves, as a result, the surface wettability increases. The methods of contact angle measurement, XPS, and ESRwere used to diagnose the surface which was exposed to the plasma at different time and different power input. The contact angle of water on the treated PTFEdrops down to about 60° comparing with 108° of the untreated PTFE. The treating effect at 180 Wor 50 Wis more efficient than at 100 W. The improvement of wettability is found to be related with the peroxide radicals formed on-the surface of PTFE.
