Abstract
A coumarin-driven switchable superhydrophobic silica surface by photochemistry is fabricated and Wenzel-Cassie wetting transition occurs on the surface under UV light (365 nm, 254 nm) irradiation. In addition, the as-prepared sample changes from random nanoparticle aggregates to necklaces (rings) through altering UV light irradiation. © 2012 The Royal Society of Chemistry.
