采用销-盘摩擦磨损试验研究了端羟基全氟聚醚薄膜在光滑硅表面的摩擦学性能。的摩擦性能的膜，其中包括物理吸附或化学键合的聚合物或两者的组合，在滑动接触和润滑剂的损失进行了研究，同时通过扫描显微椭圆偏振仪。在这些实验之前，研究了聚合物附着到硅表面的动力学和聚合物在高温下的行为，以获得润滑剂膜沉积的可再现条件，并排除膜沉积期间热降解的发生。摩擦学研究表明，与附着的边界润滑剂的表面的寿命是强烈依赖于聚合物的附着模式。最好的摩擦学行为中观察到的薄膜，其中包含化学吸附和物理吸附的材料。
The tribological behavior of ultrathin films of hydroxyl terminated perfluoropolyethers attached to smooth silicon surfaces was studied in pin-on-disk experiments. The frictional properties of the films, which consisted of either physically adsorbed or chemically bonded polymer or a combination of both, was measured in sliding contact and lubricant loss was studied simultaneously by scanning microellipsometry. Prior to these experiments the kinetics of attachment of the polymer to silicon surfaces and the behavior of the polymer at high temperatures was investigated in order to obtain reproducible conditions for the deposition of the lubricant films and to rule out the occurrence of thermal degradation during film deposition. The tribological investigations showed that the lifetime of the surfaces with the attached boundary lubricant was strongly dependent on the mode of attachment of the polymer. The best tribological behavior was observed in films which contained both chemisorbed and physically adsorbed material.
