An in situ fully light‐driven switching of superhydrophobic adhesion is demonstrated based on simply spin‐coating a hydrophobic azo‐polymer on an optimized micro‐nanopost arrayed silicon substrate. Furthermore, the detailed designing principles are discussed, which might shed light on efficient exploitation of superhydrophobic liquid/solid interfaces for smart microfluidic control.
