Wetting and Adhesion at Soft Interfaces

Liquids and solids tend to stick to each other. When a liquid droplet sticks to a solid surface we call it wetting. When a solid particle sticks to a solid surface we call it adhesion. The classic coarse-grained descriptions of these two phenomena are distinct from each other. Both descriptions assume that solid objects undergo very little deformation during wetting and adhesion. In this talk, I will show how this assumption breaks down when the solids are soft enough and how wetting and adhesion really are not that different after all.
