Abstract

Superhydrophobic Surfaces The general understanding is that droplet friction on superhydrophobic surfaces is affected by liquid–solid contact fraction. In article number 2405335, Robin H.A. Ras and co-workers experimentally quantify this relation for the first time. State-of-the-art droplet friction measurements on micropillar and -cone surfaces with significantly different contact fractions show that droplet friction depends similarly on the contact fraction on both surface types despite the large difference in the measured droplet friction.
