The new trends in corrosion control using superhydrophobic surfaces: a review

Superhydrophobic surface (SHS) fabrication has gained popularity as a corrosion prevention method for metals in recent years. Because of the vast range of sectors that are interested in and using nature-inspired biomimetic SHS, this field of advanced materials science is experiencing rapid growth. Corrosion prevention can be achieved with SHS because it effectively blocks moisture from entering. By generating an air layer between the metal and the coating, SHS provides corrosion prevention. Corrosion-inducing ions are less likely to adhere to metal surfaces with low surface energy and high surface roughness. Combining the right materials and fabrication methods allows you to fine-tune SHS's many unique features. This review article provides a survey of the superhydrophobic coatings' performances as metallic protection. Then, various models were utilized to assess the wettability of the rough surface, and the relations governing the contact angle (CA) were reported. Lastly, various methods utilized to prepare the superhydrophobic coatings and their effects on the corrosion processes for metals were also discussed.
