Abstract Because of the serious consequences of structural failures due to corrosion, research on anti-corrosion coatings has traditionally been of highest importance toward the development of sustainable durable material. Anti-corrosive coatings have played a significant role for increasing the durability of material without affecting the bulk properties and to perform its duty effectively, an anti-corrosive coating must possess intrinsic durability, adequate flexibility, adhesion and toughness to withstand impacts, cracking and appearance when subjected to stress, swell, mechanical abuse, or weathering. Exposure of metals and alloys in a humid environment may create additional challenges either to inhibit or slow down the overall corrosion rate. Despite significant improvements in corrosion coating technologies problems are continue to persist in the durable protection of metals and alloys and this is an emerging thrust area toward the development of a holistic, permanent solution for the corrosion related issues. In recent years, bio-inspired concepts of superhydrophobicity at nano-level and self-cleaning has exhibited exceptional potential as anticorrosive coatings, particularly in humid environments. With the ability to retain mechanical properties at a higher temperature and contact angle (CA) of superhydrophobic range, nano-oxides and CNTs based superhydrophobic coatings (SHCs) are gaining momentum to reach an industrial scale for real-time applications. The present article is mainly aimed to review the impact of nano-material based SHCs on metal/alloys with a concise discussion of associated challenges, potential solutions and future opportunities.

基于纳米氧化物和碳纳米管的耐腐蚀超疏水涂层的最新进展：批判性评论

摘要 由于腐蚀导致结构失效的严重后果，防腐涂层的研究历来对可持续耐用材料的开发具有最重要的意义。防腐涂层在不影响整体性能的情况下提高材料的耐久性并有效履行其职责方面发挥了重要作用，防腐涂层必须具有固有的耐用性、足够的柔韧性、附着力和韧性，以承受冲击、开裂和外观当受到压力、膨胀、机械滥用或风化时。金属和合金暴露在潮湿环境中可能会对抑制或减缓整体腐蚀速率产生额外的挑战。尽管腐蚀涂层技术有了重大改进，但金属和合金的持久保护问题仍然存在，这是为腐蚀相关问题开发整体、永久解决方案的新兴重点领域。近年来，受生物启发的纳米级超疏水性和自清洁概念在防腐涂料方面表现出非凡的潜力，尤其是在潮湿环境中。由于能够在更高的温度和超疏水范围的接触角 (CA) 下保持机械性能，基于纳米氧化物和碳纳米管的超疏水涂层 (SHC) 正在获得动力，以达到实时应用的工业规模。
