论文摘要
分析了液体蒸气宏观接触角的分析表达式，以分析底物的各种简单几何形状和排列，尤其是当后者表现出两个或多个尺度时。它涉及当底物完全湿的底物时的润湿状态，当液体悬挂在底物上时，卡西键状态，但也与另外两个相关的润湿状态也是润湿状态。在尺度假设的分离下，开发了一个接触角的组成规则，其感兴趣在近密封的雷斯伯里样颗粒中被说明。
The analytical expressions of liquid-vapor macroscopic contact angles are analyzed for various simple geometries and arrangements of the substrate, in particular when the latter exhibits two or more scales. It concerns the Wenzel state of wetting when the substrate is completely wet, the Cassie-Baxter state when the liquid hangs over the substrate, but also intermediate states of wetting which are shown to be relevant and in competition with the two other ones. Under a separation of scales hypothesis, a composition rule of contact angles is developed whose interest is illustrated in a close packing setup of rasperry-like particles.
