延长超疏水表面的使用寿命是材料实际应用的必要条件。因此，为了在使用过程中保持超疏水性所必需的微纳米级层次结构和低表面能特性，在设计表面方面已经付出了巨大的努力。结果表明，提高表面机械强度以提高耐磨性有助于保持分层粗糙度，延缓超疏水性的损失。此外，设计能够在受损时恢复其结构和/或特性的自我修复材料已经被提出并证明可以维持表面的超疏水性。本文综述了近年来在开发机械耐用、耐腐蚀、自修复和易于修复的超疏水表面方面取得的进展，这将为未来的实际应用延长超疏水表面的使用寿命。
Prolonging the lifetime of superhydrophobic surfaces is required so that the materials can be used practically. Thus, great efforts have been made in designing surfaces that maintain micro- and nanoscaled hierarchical structures and low surface-energy property, which are necessary for superhydrophobicity, during use. It was demonstrated that improving surface mechanical strength to increase wear resistance helps maintain hierarchical roughness, retarding the loss of superhydrophobicity. Additionally, designing self-healing materials that can recover their structure and/or properties when damaged has been suggested and demonstrated to sustain the superhydrophobicity of surfaces. This review focuses on recent advances in developing mechanically durable, corrosion-resistant, self-healing, and easily repairable superhydrophobic surfaces, which will enable prolonged lifetime of superhydrophobicity for practical applications in the future.
