In situ fully light-driven switching of superhydrophobic adhesion

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.
