Superhydrophobic surfaces are promising candidates for alleviating notorious corrosion phenomena due to their excellent water repellence. However, superhydrophobic surfaces often possessed with fragile structure stability as well as relatively complex fabrication processes, severely hindering their great potential for broad practical applications in various conditions. Herein, through a facile one-step spray process, a self-healing superhydrophobic coating with excellent anticorrosion performances were developed, by mixing fluorinated epoxy resin (FEP) matrix with polytetrafluoroethylene (PTFE) particles and ceresine wax. The surface maintains robust superhydrophobicity even under harsh conditions (e.g., physical impact, acid, alkali or salt solutions), hence effectively preventing corrosive ions from approaching the surface. Moreover, the superhydrophobic coating also displays remarkable self-healing performances stemming from the introduced ceresine wax, and exhibits excellent recovery of anti-corrosion performance in damaged areas after a rapid heating treatment. The combination of a superhydrophobic performance and self-healing function can significantly enhance the anticorrosion performances of coatings to provide a long-term protection for metals. Therefore, this coating may find promising applications in long-term metal corrosion protection under harsh working conditions.

具有强大自修复和防腐性能的氟化环氧树脂基超疏水涂层

超疏水表面因其出色的防水性而成为缓解臭名昭著的腐蚀现象的有希望的候选者。然而,超疏水表面通常具有脆弱的结构稳定性以及相对复杂的制造工艺,严重阻碍了它们在各种条件下广泛实际应用的巨大潜力。在此,通过简单的一步喷涂工艺,通过将氟化环氧树脂(FEP)基体与聚四氟乙烯(PTFE)颗粒和地蜡混合,开发了一种具有优异防腐性能的自修复超疏水涂层。即使在恶劣的条件下(例如,物理冲击、酸、碱或盐溶液),表面也能保持强大的超疏水性,从而有效地防止腐蚀性离子接近表面。而且,超疏水涂层还因引入地蜡蜡而表现出显着的自修复性能,并在快速加热处理后在受损区域表现出优异的防腐性能恢复。超疏水性能和自修复功能的结合可以显着提高涂层的防腐性能,为金属提供长期保护。因此,这种涂层可能会在恶劣工作条件下的长期金属腐蚀防护中找到有希望的应用。超疏水性能和自修复功能的结合可以显着提高涂层的防腐性能,为金属提供长期保护。因此,这种涂层可能会在恶劣工作条件下的长期金属腐蚀防护中找到有希望的应用。超疏水性能和自修复功能的结合可以显着提高涂层的防腐性能,为金属提供长期保护。因此,这种涂层可能会在恶劣工作条件下的长期金属腐蚀防护中找到有希望的应用。
