处于热力学和力学交叉点的软润湿和Shuttleworth效应
Soft wetting and the Shuttleworth effect, at the crossroads between thermodynamics and mechanics
摘要：
非常柔顺的弹性材料，如薄膜或软凝胶，在被液滴润湿时会变形。通常认为，“软润湿”中的固体毛细作用可以用与液体表面张力相同的方法来处理。然而，固体界面的物理化学本身受到相对于弹性参考状态的任何变形的影响。这引起了在液体中没有对应物的现象：机械表面应力不同于表面中的过量自由能。在这里，我们指出了一些引人注目的后果，这种“夏特沃斯效应”的上下文中的润湿变形基板，如外观的弹性奇点和非常规的毛细管力。我们提供了一个软润湿（微观和宏观，力学和热力学）的不同观点之间的综合，并指出在该领域的关键开放问题。
英文摘要：
Extremely compliant elastic materials, such as thin membranes or soft gels, can be deformed when wetted by a liquid drop. It is commonly assumed that the solid capillarity in "soft wetting" can be treated in the same manner as liquid surface tension. However, the physical chemistry of a solid interface is itself affected by any distortion with respect to the elastic reference state. This gives rise to phenomena that have no counterpart in liquids: the mechanical surface stress is different from the excess free energy in surface. Here we point out some striking consequences of this "Shuttleworth effect" in the context of wetting on deformable substrates, such as the appearance of elastic singularities and unconventional capillary forces. We provide a synthesis between different viewpoints on soft wetting (microscopic and macroscopic, mechanics and thermodynamics), and point out key open issues in the field.
