Understanding and harnessing the coupling between lubrication pressure, elasticity, and surface interactions provides materials design strategies for applications such as adhesives, coatings, microsensors, and biomaterials. This presentation will discuss our efforts tounderstand how soft materials make contact and adhere under dynamic conditions in fluid environments. Measurements of interactions between soft surfaces will show how elastic films deform due to viscous forces and influence adhesion. In particular, we will discuss conditions dominated by viscous or surfaces forces. We will show qualitative differences in debonding mechanism caused by the elasticity of the substrate.
