Abstract
The present application relates to multifunctional hierarchically microstructured surfaces and three-dimensional anchored interfacial domain structures. The multifunctional properties are extremal. In one aspect the microstructured surfaces may be super-adhesive. Examples of super-adhesive mechanisms may include gas trapping, fluid trapping, and solid wrinkle trapping. In another aspect the micro structured surfaces may be nearly adhesive-less. Examples of adhesive-less mechanisms may include inter-solid surface lubrication, energy conserving fluid flows, and super-low drag phase-phase lateral displacement. The extremal structures may be obtained by anchoring mechanisms. Examples of anchoring mechanisms may include Wenzel-Cassie formation, contact angle confusion, and capillary effects.
