Light-induced switching of surfaces at wetting transitions through photoisomerization of polymer monolayers.

Abstract

We report on a method to generate surfaces whose wettability can be reversibly switched between a superhydrophobic and Wenzel state or a Wenzel and superwetting state just by a short UV or VIS irradiation. To achieve this, we generate a silicon surface with a nanoscale roughness ("black silicon") and attach a polymer monolayer to it. The polymer contains a… (More)
