Abstract: A superhydrophobic surface includes a plurality of microfeatures disposed on a substrate and a gas generator disposed within the microfeatures, the gas generator configured to generate a gas within the microfeatures. Gas is generated within the microfeatures when at least a portion of the microfeatures is in a wetted state to restore the microfeatures to a dewetted state. Gas generation is self-regulating in that gas generation automatically starts when a wetted condition exists and stops when sufficient gas has been generated to recover a dewetted state that restores superhydrophobicity.
