Science and Engineering of Superhydrophobic Surfaces: Review of Corrosion Resistance, Chemical and Mechanical Stability

Investigations on superhydrophobic surfaces (SHS) are very interesting because of their importance in many applications. One of the major applications of these SHS is to increase the corrosion resistance of surfaces exposed to corrosive environments as well as their long-term chemical stability and maintaining the superhydrophobic characteristics. Deep understanding of how to increase the corrosion resistance by SHS has a significant effect on the development of strategies to improve corrosion resistance and long-term chemical stability of these surfaces. Other important properties that limited the real use of superhydrophobic surfaces are mechanical stability. In this review article, an overview of SHS is provided, and then their fabrication methods discussed. Moreover, the corrosion resistance of these SHS fabricated by various methods and their chemical stability and mechanical stability are reviewed. -In the following, recent strategies for improvement of corrosion resistance, chemical and mechanical stability are reviewed.
