Although self-healing superhydrophobic surfaces have .aroused much attention due to their repairable wetting properties and wide applications, the realization of dual healing of both microstructure and surface chemistry remains challenging. Herein, we develop a novel superhydrophobic surface composed of a shape memory micropillar array decorated by pH-responsive capsules encapsulated with fluoroalkylsilane. Owing to the shape memory effect of micropillar and the encapsulated surface chemistry healing agent fluoroalkylsilane, the obtained surface can not only repair the damaged surface chemistry after acid stimuli, but also restore the crushed surface microstructures by heat.
