对全氟聚醚 (PFPE) 薄膜的动态行为进行了严格的审查。提出了一种从扫描微椭圆光度 (SME) 实验中提取铺展信息的方法，以研究各种 PFPE 在二氧化硅和碳表面上的补充特性。此外，还讨论了 SME 测量、表面能（或分离压力）、流变学和摩擦学之间的关系。麦克斯韦的等面积结构被引入到分离的压力-高度等温线中，以将表面能与 SME 轮廓相关联。在小的高度（h）处存在定性相关性，随着h变大，这种相关性变得不一致。使用氢化和氮化碳外涂层膜的例子来说明这一点。
The dynamic behavior of thin perfluoropolyether (PFPE) films is critically reviewed. A methodology for extracting spreading information from scanning microellipsometry (SME) experiments to investigate the replenishment characteristics of various PFPEs on silica and carbon surfaces is presented. Furthermore, the relationship among SME measurements, surface energy (or disjoining pressure), rheology, and tribology is discussed. Maxwell's equal area construction is introduced into the disjoining pressure-height isotherm to correlate surface energy with the SME profile. There is a qualitative correlation at small height (h), which becomes inconsistent as h becomes large, Examples with hydrogenated and nitrogenated carbon overcoat films are used to illustrate this point.
