Abstract

The evolution of the “local triple-phase contact line” with increasing droplet volume on a micropillared superhydrophobic surface, from (a) the initial contacting stage to (b) the pinning stage to (c) the depinning stage. (d) The sketch of the evolutionary process of local contact angles.
