“…Durability is an important criterion for evaluating whether superhydrophobic surfaces can be used in practice. Jia et al synthesized PDMS-SiO 2 nanoparticles through a hightemperature dehydration reaction and then prepared a super-hydrophobic coating, but this coating tends to fail in harsh environments [32]. In this study, we tested the durability of the prepared superhydrophobic coating through a series of experiments.…”

A facile and cost-effective layer-by-layer assembly method is reported for the fabrication of a superhydrophobic coating using room temperature vulcanized silicone rubber and silica particles of different diameters. The superhydrophobic coating shows a contact angle of 154.6° and a rolling angle of 9°. The coating exhibits excellent self-cleaning properties and corrosion resistance with good softness and mechanical durability. The sample maintains its good superhydrophobicity, even after a series of tests by knife scratching, cutting, and hammering. The fabrication method has great advantages in terms of efficiency, cost, simple procedure and conditions. Its wide application in different substrates and the use of environment-friendly materials are also beneficial to the large-scale production of the coating.

“…Because of its low surface energy, resistance to oxidation, good low-temperature performance, and environmental benefits, poly(dimethylsiloxane) has been widely used in many applications such as furfural separation, , medical implants, and functional surfaces with anti-frosting and deicing properties. − In this work, coatings made of hydroxyl-terminated dimethylsiloxane and the cross-linker tetramethoxysilane (TMOS) were fabricated on a glass substrate by manual spraying. The morphology and wettability of the surface were characterized, and its large-scale deicing properties were investigated comprehensively.…”

Icing of surfaces has become a serious issue, and effective methods for preventing ice accretion have received much attention in recent years. Here, a solvent volatilization-induced cross-linking hydroxy-terminated dimethylsiloxane (Si−OH) coating with tetramethoxysilane (TMOS) as a cross-linker is proposed for large-scale deicing applications. Interfacial adhesion tests and shear force analysis were conducted to confirm the large-scale deicing properties of the polydimethylsiloxane (PDMS) coating. Through characterization of morphology, it was found that there were negative correlations between roughness and constant shear force and shear strength. The mean constant shear force per unit width could be lower than 14 N/cm when the roughness was in the highest range fabricated in this research. In addition to the morphology of the surface, the mass ratio of the cross-linker to the premonomer affected the state of the surface and the deicing properties. When the mass ratio was lowered, uncross-linked molecular chains of the premonomer existed on the surface, which resulted in an increase in interfacial toughness and a reduction in shear strength. Finally, durability tests showed that the coating had excellent durability and could endure at least 50 cycles without an apparent increase in the constant shear force.

“…Inspired by the unique water repelling nature of lotus leaves, superhydrophobic surfaces have been extensively explored for various potential applications, such as anti-fogging, antiicing, anti-corrosion, oil/water separation, self-cleaning and anti-contamination, etc. [1][2][3][4][5][6][7]. Superhydrophobic surface has a water contact angle (WCA) higher than 150 • and a water rolling angle less than 10 • .…”

In this work, polyurethane/fluorinated acrylic co-polymer/silicon dioxide (PU/FAP/SiO2) hybrid superhydrophobic coatings were fabricated on glass substrates via a simple one-step coating process. The effects of each coating component on the coating properties were systematically investigated. The optimized coating exhibits a water contact angle (WCA) of 159° and a rolling angle of 3°. Meanwhile, the coating has an optical light transmittance of 88%, indicating the good transparency of the coating. Besides, the coating demonstrates an adequate level of abrasion resistance. After a total abrasion distance of 300 cm against a piece of 800 mesh sand paper, the sample still kept a water contact angle of about 110°, showing its high abrasion resistance. Therefore, the optimized coating has a great potential for practical application.
