Abstract
A microstructured pressure-sensitive surface is described comprising a Wenzel-Cassie hydrophilic-hydrophobic zone structure and capillary action with improved peel strength. The capillary action is enhanced by the Wenzel-Cassie zone creation, and the barrier energy to disruption of the Wenzel-Cassie zone is increased by the capillary action. The micro-structured surfaces of the present invention create water zones of exclusion, where entropic effects reinforce Wenzel-Cassie zone stability, creating a suction effect that conforms the microstructure surface to a target surface.
