Mechanical Durability of Engineered Superhydrophobic Surfaces for Anti-Corrosion

Engineered superhydrophobic coating for anti-corrosion applications is a subject of great significance at present. However, the use of superhydrophobic coatings for anti-corrosion applications is hindered by the mechanical durability in many cases. There is a need for an understanding not only of how to fabricate such surfaces, but also of the corrosion resistance and mechanical durability of those coatings. This review discusses recent developments in the mechanical durability of superhydrophobic coatings primarily used for anti-corrosion. First, superhydrophobicity is introduced with an emphasis on different wetting models. After that, this review classifies the nanofabrication methods based on the material and methods of surface functionalization. Furthermore, the testing procedures used for the measurement of corrosion and mechanical durability are presented. Finally, the mechanical durability and anti-corrosion performance of the developed superhydrophobic coatings are discussed.
