A bio‐inspired honeycomb pattern that exhibits shape memory behavior is successfully fabricated via the breath figure process. By the surface modification along with a chemical crosslinking process to enhance the recoverability, this honeycomb‐like structure with shape memory behavior is realized. The surface wettability is dependent on the surface topography controlled by the deformation of temporary shape (elliptical circle) and recovery of the permanent shape (round circle) at the microscopic scales without the need of micromolding or expensive lithography strategy. This approach opens a facile route to an efficient, inexpensive, and versatile method to prepare films with switchable wettability.
