| 近年来，随着现代工业不断发展，金属材料的应用日趋广泛，同时金属材料的腐蚀问题也受到大家的广泛关注。超疏水化合物因其优良的化学特性而被应用于金属腐蚀防护领域。介绍了超疏水化合物在金属基底进行防护的原理，综述了近年来常用于制备超疏水表面的方法，如通过氟化物、硬脂酸类化合物、长链的烷基或者是硅烷基等疏水性物质对低表面能的化合物进行改性，构建出具有低表面能的超疏水表面。超疏水化合物与有机金属框架化合物(MOFs)、缓蚀剂以及微胶囊3种特殊的具有防腐特性的物质，可通过协同作用对金属基体进行防护:(1)利用一些疏水性化合物对具有特殊的表面特性的有机金属框架化合物(MOFs)纳米材料进行改性，制造出超疏水表面;(2)通过一些长链疏水性化合物对缓蚀剂进行改性，以提高其疏水性能，进而可获得更优异的防腐效果;(3)具有自修复功能的微胶囊与疏水性化合物，通过协同作用发挥其最佳防腐性能。最后对超疏水化合物在金属腐蚀与防护领域的应用前景进行了展望。 |

| In recent years, with the continuous development of modern industry, the applications of metal materials are becoming more and more extensive. At the same time, the corrosion of metal materials is also widely concerned. Superhydrophobic compounds are used in the field of metal corrosion protection because of their excellent chemical properties. In this paper, the principle of superhydrophobic compounds protection on metal substrate are introduced, and the methods of preparing superhydrophobic surface commonly used in recent years are summarized. For example, the compounds with low surface energy are modified by fluorides, stearic acids, long-chain alkyls or silyl group to build superhydrophobic surface with low surface energy. Superhydrophobic compounds, organic metal framework compounds (MOFs), corrosion inhibitors and microcapsules can protect the metal matrix through synergistic action:(1) Some hydrophobic compounds are used to modify the organic MOFs with special surface properties to produce superhydrophobic surfaces; (2) The inhibitors are modified by some long-chain hydrophobic compounds to improve their hydrophobicity so as to obtain the better anticorrosion effect; (3) Microcapsules with self-healing function and hydrophobic compounds can exhibit the best anti-corrosion performance through synergistic action. The applications of superhydrophobic compounds in metal corrosion and protection are prospected. |
