In-situ switchable superhydrophobic shape memory microstructure patterns with reversible wettability and adhesion

A novel patterned superhydrophobic surfaces with shape memory performance is reported. Based on the shape memory ability in surface microstructure, the surface pattern and corresponding wettability can be reversibly controlled between various states, such as high/low adhesions and isotropic/anisotropic wettings. And the patterned surface has special advantages compared with traditional hydrophilic patterns such as anti-pollution property and excellent stability were also demonstrated.
