Smart superhydrophobic surfaces with reversible wettability are attracting increasing attention. However, most of the reported wettability transitions of smart superhydrophobic surfaces are mainly made through reversible changing surface chemistry. There are few reports that the wettability of superhydrophobic surfaces can be changed reversibly by changing the surface microstructures, and the manufacturing of smart superhydrophobic surfaces with microstructure is still a great challenge. Due to shape memory polymer (SMP) and their composites have many advantages such as various driving modes, excellent shape recovery performance and mechanical properties, in this work, the template method was used to prepare switchable wettability smart superhydrophobic surface with strip microstructure arrays based on thermally responsive shape memory polymer and to explore the potential application prospect of the surface. And wettability reversible conversion ability and cycling stability were tested. Firstly, the aluminum template with strip microstructure arrays was fabricated by wire cutting. Secondly, the silica gel template was used as the intermediate template to prepare the smart superhydrophobic surface with strip microstructure arrays. The silica gel template can be used for many times during the preparation, and it was easy to demould during the preparation and could ensure the integrity of the surface microstructure arrays. By observing the smart superhydrophobic surface with a scanning electron microscope, it was found that its microstructures were intact and its contour was clear. The contact angle of droplets on this surface could reach (150±3)°.
