Abstract
We report an approach to restore a gas layer on superhydrophobic surfaces by (i) implementing self-regulating gas generation and (ii) designing surface structures that allow the gas propagation along the surface. Restoration of a gas layer is successfully demonstrated on two surface patterns - mico posts and grates. The present approach is shown to work even under harsh conditions such as a high liquid pressure and defective surfaces.
