Abstract

The surfaces of two engineering polymers including polyamide 66 (PA66) and polytetrafluoroethylene (PTFE) were treated by diffuse coplanar surface barrier discharges in atmospheric air. We found that plasma treatment improved the adhesion of PA66 for either polymer/polymer or polymer/steel joints, however, it was selective for the investigated adhesive agents. For PTFE the adhesion was unaltered for plasma treatment regardless the type of used adhesive. Tribological properties were slightly improved for PA66, too. Both the friction coefficient and wear decreased. Significant changes, again, could not be detected for PTFE. The occurred variation in the adhesion and tribology was discussed on the basis of the occurred changes in surface chemistry, wettability and topography of the polymer surface.

摘要

两种工程聚合物，即聚酰胺66（PA66）和聚四氟乙烯（PTFE）的表面，在大气空气中通过扩散共面表面屏障放电进行了处理。我们发现，等离子体处理改善了PA66在聚合物/聚合物或聚合物/钢接头中的粘附性，然而，它对所研究的粘合剂具有选择性。对于PTFE，无论使用何种类型的粘合剂，等离子体处理后的粘附性都没有改变。PA66的摩擦学性能也略有改善。摩擦系数和磨损都降低了。同样，未检测到PTFE有显著变化。基于聚合物表面化学、润湿性和形貌的变化，讨论了粘附性和摩擦学中出现的变化。
