“…Typically, manual cleaning is costly and hostile to the environment because it requires a lot of water and detergents. Researchers have demonstrated several active and passive self-cleaning techniques for maintaining the conversion efficiency of PV panels [4][5][6][7][8][9][10][11].…”

Superhydrophobic coatings are gaining popularity because of their low maintenance requirements, high durability, and wide range of potential uses. Such coatings, for instance, may provide beneficial resistance to fouling, icing, smear, and corrosion, and can separate oil from water. Therefore, the creation of superhydrophobic materials is a topic of great interest to academics all around the world. In this paper, a spray-coating deposition technique is used to deposit silica nanoparticles on glass while using a sol–gel as a base. The applied coating increased the transmittance to 99% at 600 nm. Water contact angle (WCA) and scanning electron microscopy (SEM) observations of the coated layer’s grade index and induced porousness led to superhydrophobic behavior with a water contact angle that was higher than 158°.

“…At present, the relatively mature methods to prepare superhydrophobic surfaces mainly include the template method [8,9], the layer-by-layer self-assembly method [10,11], the deposition method [12], the electrostatic spinning method [13], the etching method [14], the phase separation method [15], and so on. A superhydrophobic surface has excellent hydrophobicity, and its special wettability makes superhydrophobic surfaces widely used in self-cleaning [16], anti-icing [17], anti-corrosion [18], oil-water separation [19], and other fields. At present, more and more scholars are conducting research in the field of superhydrophobicity and are trying to prepare superhydrophobic surfaces in novel ways.…”

Superhydrophobic materials have a good application prospect in self-cleaning, anti-fouling, anti-corrosion, and anti-freezing. However, creating large areas of simple, efficient, and environmentally friendly superhydrophobic surfaces remains a huge challenge. In this paper, a simple, environmentally friendly surface superhydrophobic preparation method is used based on 107 silicone rubber adhesive. A superhydrophobic coating with a micro/nano structure was constructed on the surface of fluorine rubber. The particle size and groups of HB-192V powder (mainly SiO2) were observed by Fourier-transform infrared spectroscopy and a scanning electron microscope (SEM). The structures of two kinds of rubber surfaces were observed by SEM, and the superhydrophobic surface materials were qualitatively analyzed by X-ray diffraction (XRD). The hydrophobic properties of the superhydrophobic surface and the bouncing properties of droplets were analyzed by a contact angle measuring instrument and a high-speed camera. The results show that the preparation of superhydrophobic fluorine rubber on the surface of the water meter contact angle could reach an average of 154.1°. The superhydrophobic surface prepared by this method has a better hydrophobic and droplet bounce property.

Super‐hydrophobic surface has excellent waterproof, self‐cleaning and delayed icing properties, and is widely used in various fields, but its lack of durability restricts its large‐scale use. In this paper, carbon fiber composite material with excellent mechanical properties is selected as the substrate, PTFE nanoparticles with excellent hydrophobicity are used as the surface energy substance, and metal screen is selected as the template, combined with hot pressing molding process, a super‐hydrophobic surface with multi‐level micro‐nano structure is successfully constructed. The test shows that the water contact angle of the surface is 169°, and the rolling angle is about 2°. The contact angle of the surface is also over 150° for other liquids, and it bounces off the external water droplets for three times, so it can easily take away pollutants and keep the surface dry and clean under the action of water flow. In the same icing environment, compared with the original surface, it can prolong the freezing time of droplets by 5 times. After repeated rubbing, the surface still has superhydrophobic properties until the whole surface is completely destroyed. The preparation method used in this study is simple, and the prepared superhydrophobic surface has excellent performance, which is expected to promote the application of superhydrophobic surface in practical working conditions.Highlights The preparation method is fast, efficient, low‐energy and environment‐friendly, and the used materials are simple and economical, and can be reused. The prepared surface has excellent hydrophobic performance for different media. The prepared superhydrophobic surface has low adhesion and droplet rebound performance. The prepared superhydrophobic surface has excellent delayed icing performance. The prepared superhydrophobic surface has excellent wear resistance.
