| Abstract: |
| Increasing the hydrophobicity of materials surfaces can reduce their interactions with corrosive media such as water, thereby enhancing their corrosion resistance. In recent years, superhydrophobic surfaces have received widespread attention because of its non-wetting and self-cleaning surface properties. A growing number of studies have been focused on applying superhydrophobic surfaces for anticorrosion purposes. Wettability on the surface of the material mainly depends on the surface chemical properties and surface microstructure, thus improvement of the material surface hydrophobicity is often achieved by lowering the surface energy and changing the surface microscopic structure. This article expounds the mechanism of wettability on superhydrophobic surfaces, introduces different methods for establishing a rough surface microstructure and reinforcing material hydrophobic/ super hydrophobic property, summarizes the recent progresses and the existing problems in superhydrophobic anticorrosive surface technologies in the field of corrosion protection, and prospects the future development of superhydrophobic anticorrosive surface technologies. |
