From: Wettability Switching Techniques on Superhydrophobic Surfaces
Schematic illustration of the process used to adjust contact angles. The scheme shows the different stages of the wetting behavior: (a) the nanotube surface; (b) superhydrophobicity after hydrophobic modification; (c) chain scission of the organic layer triggered by UV light and (d) leading finally to complete wetting.
