The concept, deposition routes, and applications of superhydrophobic surfaces – Review

Abstract

The superhydrophobic surface (SHS) is the surface with a high apparent contact angle (> 150 °), low hysteresis in the contact angle (< 10 °), and low sliding angle. Owing to many applications of SHS (such as water-resistant surfaces, antifogging surfaces, anti-icing surfaces, anticorrosion surfaces, etc.), the artificial SHS could be prepared. This review article focuses on the deposition, behavior and application of the SHS. It includes an introduction, fundamental principles of superhydrophobicity, main factors for SHS fabrications, deposition methods used to prepare the SHS, and factors affecting the electrochemical synthesis of electroconducting polymers. Moreover, the mechanism of the electrochemical synthesis of polymers, applications of SHS in different fields, and the stability of SHS have been presented. Finally, the challenges of SHS have been discussed.
