| Abstract: | We have fabricated superhydrophobic zinc surface with reversible transformation between sliding state and adhesion by a simple hydrothermal method. Uniformly ZnO2 nanorod was obtained at 120°C. After self-assembling of a film of n-octadecanethiol, the surface with a water contact angle (CA) of 153 ± 2°, exhibited a nonwetting property. The surface showed switchable adhesion just upon introducing UV illumination and heating treatment in turn. |
