Herein is described a facile, in situ, ink‐regulating approach to rapidly achieve reversible water wettability and adhesion transition, with a large degree of contrast, on superhydrophobic TiO 2 nanotube array film. The ink printing and removal process allows the wettability and reversible adhesion transitions to be realized. Experimental results demonstrate the potential application of such site‐selective, sticky superhydrophobic patterns for droplet manipulation by in situ surface modification.
