Application of copolymerization in preparation of superhydrophobic surfaces

Abstract

Superhydrophobicity refers to a wetting phenomenon in which the contact angle with water is greater than 150°and the sliding angle is less than 10°. Superhydrophobic surfaces have been extensively studied due to its self-cleaning, corrosion resistance, anti-icing, oil-water separation and other characteristics. Among the studies, copolymerization is one of the important methods in the preparation of superhydrophobic surfaces. In this paper, the mechanism of superhydrophobicity and the models are introduced. Then, in view of the three ways to obtain superhydrophobic surfaces through copolymerization - modification, directly synthesis of superhydrophobic Copolymer, preparation of superhydrophobic coatings or coatings - the methods are summarized, and the related applications are briefly described. Finally, possible future researching directions are summarized and prospected to provide reference for the application of copolymerization in preparation of superhydrophobic surfaces.
