Biomimetic control of wetting and adhesion

We have explored the cuticular morphology and chemistry of liquid-repellent cuticula of springtails (Collembola), arthropods living in the soil, and derived general design criteria for robust omniphobic surfaces. The resistance of the cuticle against wetting and its mechanical stability were shown to depend on a combination of overhanging cross-sections and their arrangement in a self-supporting comb-like pattern, features that we could successfully translate into robust omniphobic polymer membranes that can be even applied to curved surfaces.
