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.

具有可恢复的微结构和自修复表面化学的智能超疏水表面。

尽管自修复的超疏水表面由于其可修复的润湿性能和广泛的应用引起了人们的广泛关注，但实现微观结构和表面化学的双重修复仍然具有挑战性。在这里，我们开发了一种新型的超疏水表面，该表面由形状记忆微柱阵列组成，该阵列由装饰有氟代烷基硅烷的pH响应胶囊装饰。由于微柱的形状记忆作用和封装的表面化学愈合剂氟代烷基硅烷，所获得的表面不仅可以在酸刺激后修复受损的表面化学，而且可以通过加热恢复破碎的表面微观结构。
