Application of self-assembly methods in the preparation of superhydrophobic surfaces: A review

Superhydrophobic surfaces have attracted considerable interest due to their unique properties such as selfcleaning, corrosion resistance, anti-icing and drag reduction. However, the poor durability of superhydrophobic surfaces significantly limits their practical application. Bio-inspired self-assembly methods have emerged as a promising approach to prepare superhydrophobic surfaces due to their convenience in modulating surface chemistry and morphology. This paper summarises the methods and strategies employed in the fabrication of superhydrophobic surfaces via self-assembly. It reviews recent research advances in this field, with a particular emphasis on the development of self-healing superhydrophobic surfaces using self-assembly techniques. Then the applications of self-assembled superhydrophobic surfaces are introduced in detail. Finally, the challenges and prospects of self-assembly for the preparation of superhydrophobic surfaces are also discussed.
