Abstract:

The superhydrophobic surface have been studied for decades, and the applications of superhydrophobic metal materials in chemical engineering are quite promosing. In this work, the latest progress in the preparation of superhydrophobic metal surface materials and their applications are reviewed. On the basis of fundamental wetting models, the preparation methods of constructing rough micro- and nano-structure on metal for obtaining superhydrophobic surface are introduced. Applications of superhydrophobic metal surface in conventional chemical engineering such as self-clean, drag reduction, heat exchanging intensification, anti-icing, anti-corrosion, water/oil separation, and new applications including anti-scaling, rolling granulation, and evaporation crystallization, are summarized. Finally, the developing tendency is proposed as one-step preparation of stable and high-performance superhydrophobic metal surface with the features of pollution-free, low-cost, and quickness.

Key words: superhydrophobicity, metal, preparation, application, stability
