先在铝基体上制备了镁铝水滑石膜层和十钒酸根插层水滑石膜层两种类水滑石膜层，再采用全氟辛基三乙氧基硅烷通过气相沉积法对类水滑石膜层进行不同时间的表面改性，制备出超疏水类水滑石膜层。采用扫描电子显微镜、接触角测量仪对膜层的结构和润湿性进行分析，讨论了改性时间对膜层结构和超疏水性能的影响，并且通过电化学测试，短期浸泡试验及盐雾试验进一步研究了该超疏水膜层的耐蚀性。结果表明：改性1 h即可使类水滑石膜层获得超疏水性能，随着改性时间的延长，超疏水膜层的接触角基本不变，12 h为最佳改性时间；超疏水膜层可以极大提高基体的耐蚀性，其中装载钒酸盐缓蚀剂超疏水类水滑石膜层的耐蚀性远高于单纯超疏水类水滑石膜层的。

Two kinds of hydrotalcite-like films including Mg-Al hydrotalcite film and decadexanadate intercalated hydrotalcite film were prepared on aluminum substrate. Then super-hydrophobic hydrotalcite-like films were prepared by surface modification to hydrotalcite-like films using perfluorooctyl triethoxy silane and through vapor deposition method. Scanning electron microscopy (SEM) and contact angle measuring instrument were used to analyze the structure and wettability of the films. The effects of modification time on the structure and super-hydrophobic properties of the films were discussed. Electrochemical test, short-term immersion test and salt spraying test were carried out to study the corrosion resistance of the prepared super-hydrophobic films. The results show that the hydrophobic films could obtain super-hydrophobic property when modified for 1 h. With the extension of modification time, the contact angles of the super-hydrophobic films were basically unchanged, and 12 h was the best modification time. The super-hydrophobic films could greatly improve the corrosion resistance of the substrate. And the corrosion resistance of the super-hydrophobic hydrotalcite-like film installed with inhibitor of vanadate was much better than that of the pure super-hydrophobic hydrotalcite-like film.
