“…Other than TMOS, various silane regents with hydrophobic moieties such as octadecyltrichlorosilane (OTS), 1H,1H,2H,2H ‐perfluorooctyltrichloro silane, and hexamethyl‐disilazane have been used to chemically modify the substrates. Liu et al had synthesized dahlia‐like Co 3 O 4 nanoparticles on nickel foam via a hydrothermal method, and the material was further modified with heptadecafluoro‐1,1,2,2‐tetrahydro‐decyl‐1‐trimethoxysilane (FAS‐17) to obtain a low surface energy material with oleophobicity and superhydrophobicity . In addition to simple and one‐step modification, silane reagents terminated with different functional groups such as amine, carboxyl, thiol, alkene, alkyne can be used for specific functionality.…”

Understanding the relationship between liquid manipulation and micro‐/nanostructured interfaces has gained much attention due to the wide potential applications in many fields, such as chemical and biomedical assays, environmental protection, industry, and even daily life. Much work has been done to construct various materials with interfacial liquid manipulation abilities, leading to a range of interesting applications. Herein, different fabrication methods from the top‐down approach to the bottom‐up approach and subsequent surface modifications of micro‐/nanostructured interfaces are first introduced. Then, interactions between the surface and liquid, including liquid wetting, liquid transportation, and a number of corresponding models, together with the definition of hydrophilic/hydrophobic, oleophilic/olephobic, the definition and mechanism of superwetting, including superhydrophobicity, superhydrophilicity, and superoleophobicity, are presented. The micro‐/nanostructured interface, with major applications in self‐cleaning, antifogging, anti‐icing, anticorrosion, drag‐reduction, oil–water separation, water collection, droplet (micro)array, and surface‐directed liquid transport, is summarized, and the mechanisms underlying each application are discussed. Finally, the remaining challenges and future perspectives in this area are included.

“…The cleaned magnesium alloy was placed into an autoclave that included 20 mL of deionized water for 2-5 h at 160 • C and formed a porous structure, which is shown in Figure 7a-d. Zhou et al prepared superhydrophobic TiO 2 films on glass for self-cleaning and anti-icing [52]. The titanium tetraisopropoxide was used as the titanium source and dissolved in the solution of 15 mL of HCl and 15 mL of deionized water; the glass was placed at an angle of 45 • on the wall of the autoclave and reacted for a certain time at 150 • C. As a result, TiO 2 nanorods can be generated; the morphologies of different samples can be seen in Figure 7e-g. Chen et al synthesized Dahlia-like Co 3 O 4 nanoparticles on porous nickel foam for water-oil separation via the hydrothermal method [53]. The production procedure can be seen from the reference in detail.…”

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.

“…Thus it is necessary to develop a self-cleaning, wear-resistant and transparent mobile phone screen, and superwetting materials are one of the choices of mobile phone screen coatings. Super-wetting materials have good anti-current conduction, anti-corrosion, waterproof, anti-fog, antimold, anti-snow, anti-freeze, anti-sticking, anti-pollution, and resistance reduction qualities, and other functions [1][2][3][4][5][6] which have a wide range of application prospects in the fields of transportation, clothing and textiles, liquid transportation, biomedicine, daily necessities and packaging, construction, and microanalysis [7][8][9][10][11]. Transparent superhydrophobic materials can be used in field lenses, car glass, curtain walls, mobile phone screens, and other occasions, and have anti-fouling, anti-fog, and waterproof properties [12][13][14][15], which can increase the safety and reliability of equipment, and is a special coating that is widely used.…”

Transparent superhydrophobic materials can be used in car glass, curtain walls, mobile phone screens, and other items. However, the hydrophobicity, transparency, and abrasion resistance of the transparent superhydrophobic coating are mutually restricted, and it is difficult to prepare transparent superhydrophobic coating with good performance. In this article, taking the mobile phone screen transparent coating as the research object, the inorganic silicon resin crystal coating as the main material, and the organic silicon resin as the binder and the hardness regulator, with the addition of the hydrophobically modifying nano silica particles, a high-transparent, wear-resistant, and superhydrophobic coating is researched. Experiments showed that when the composition mass ratio of SJ-32F resin to 9825 resin is 9:1 and the mass ratio of modified nano silica is 1.7%, the coating has a hardness of 3H–4H suitable for mobile phone screens, the contact angle of the coating can reach more than 150°, the rolling angle is less than 10°, and the light transmittance of the coating remains high at 91–95%. The cross-hatch adhesion strength of the coating reaches 5B, and the average adhesion strength measured by the adhesion pull tester is about 5.4 MPa. When the rubbing times reached 100, the light transmittance of the coating remained above 80%, and the contact angle remained basically unchanged.
