Invisible Gates for Moving Water Droplets: Adhesive Force Gradients on a Biomimetic Superhydrophobic Surface
Source abstract
Abstract
On a hybrid surface, a gradient in the areal number density of metal domes generates an adhesive force gradient (AFG) that divides the surface into areas of water droplet sliding and adhesion. We demonstrate droplet-mass-dependent pinning of sliding water microdroplets on a tilted AFG hybrid surface. The pinning location acts as an invisible gate for the sliding water microdroplets.
