“…There are a variety of methods to construct hierarchical micro/nanostructures. Qing et al developed a robust superhydrophobic surface using sandpaper as a template to lock in the fluorinated inorganic/organic film, which demonstrated exceptional mechanical robustness, good pressure stability, and repellency to hot water [77]. Zhang et al prepared a zeolite antireflective (ZAR) coating via the layer-by-layer (LBL) method [78]; they created micro and macroporous structures to realize antireflective property.…”

Superhydrophobic surfaces have drawn attention from scientists and engineers because of their extreme water repellency. More interestingly, these surfaces have also demonstrated an infinite influence on civil engineering materials. In this feature article, the history of wettability theory is described firstly. The approaches to construct hierarchical micro/nanostructures such as chemical vapor deposition (CVD), electrochemical, etching, and flame synthesis methods are introduced. Then, the advantages and limitations of each method are discussed. Furthermore, the recent progress of superhydrophobicity applied on civil engineering materials and its applications are summarized. Finally, the obstacles and prospects of superhydrophobic civil engineering materials are stated and expected. This review should be of interest to scientists and civil engineers who are interested in superhydrophobic surfaces and novel civil engineering materials.

“…Y. Qing et al have prepared the modified TiO 2 particles (FAS-TiO 2 ) by hydrothermal reaction process with CA of 160.6 and SA of 3.9 . FAS-TiO 2 /PDMS superhydrophobic sandpaper surface (FTPSS) exhibit excellent self-cleaning and anti-snow/anti-icing performance even after 50 abrasion cycles with sandpaper and prevented snow and ice from adhering to the substrate (Qing et al 2019). K. Chen et al have reported the UV and pH dual stimuli-responsive self-repairing water-based superhydrophobic TiO 2 coatings which were prepared by spray process using perfluorooctyltriethoxysilane (FAS13) with WCA of 155.3 (Chen et al 2017).…”

This chapter is based on the recent literature on the superhydrophobic surface coated using various kinds of nanostructured materials (such as metal oxide and composite) and surface functionalizaton. Superhydrophobic surfaces repel water generally due to their surface texture or chemical properties, and surface possesses a high apparent contact angle (>150) and very low sliding angle (<5). Superhydrophobic coatings have received great attention worldwide for its multifunctional application in automotive, marine, and building sector.

“…12,13 Many researchers have endeavoured to develop various methods and materials to mimic the lotus-leaf-like structures to obtain the superhydrophobic surfaces. [14][15][16][17][18][19] The micron-scale structures on lotus leaves, i.e., epidermal cells covered with the papillae, can be feasibly prepared with high delity by different microfabrication methods. On the other hand, the surface nanostructures from extracellular cuticles can only be laboriously mimicked by special methods, such as surface roughing treatments in following processes to obtain higher hydrophobicity.…”
