通过使用扫描微椭圆计对新型环三磷嗪封端的全氟聚醚（PFPE）薄膜在碳表面上的铺展特性进行了实验研究。为了评估扩散速度，还研究了新型润滑剂的表观扩散系数，并将其与传统的 Zdol 进行了比较。结果发现，环三磷嗪封端的 PFPE 薄膜的迁移率低于 Zdol。该特性取决于润滑剂的端基和碳表面之间的相互作用，并且发现润滑剂的粘附功趋势与润滑剂的流动趋势具有良好的相关性。此外，还确定了新型润滑膜和传统 Zdol 的单层膜厚度，并使用 Matano 界面方法提取。因此，可以根据单层膜厚度结果估计碳表面上新型环三磷嗪封端的 PFPE 膜的现有构象。
Spreading characteristics of novel cyclotriphosphazine-terminated Perfluoropolyether (PFPE) films on carbon surfaces were investigated experimentally by using a scanning micro-ellipsometer. The apparent diffusion coefficients of novel lubricants were also studied in order to evaluate the spreading speed and they were compared with the conventional Zdol. It was found that the mobility of cyclotriphosphazine-terminated PFPE films is lower than that of Zdol. This characteristics is dependent on the interactions between the end groups of the lubricants and carbon surfaces and it is found that the tendency of work of adhesion for the lubricants has a good correlation with the mobility tendency of the lubricants. In addition, the monolayer film thickness of novel lubricant films as well as conventional Zdol was identified, which was extracted using Matano interface method. As a result, the existing conformation of novel cyclotriphosphazine-terminated PFPE film on carbon surfaces could be estimated, based on the monolayer film thickness results.
