“…The high-resolution spectral analysis for the B element on the surface of modified BN (Figure b) shows that the B1s peak can be decomposed into two Gaussian curves, one of which is from the binding energy of the B–N bond of BN itself (190.4 eV); the other is from the binding energy of B–O brought by −OH after NaOH attack (190.9 eV). For high-resolution spectrum analysis in F-SiC (Figure c), the Si2s peak can be deconvolved into three Gaussian curves, corresponding to Si–O–Si (102.4 eV), Si–C (103.1 eV), and Si–O–C (104.4 eV) . Similarly, the B element (Figure d), N element (Figure e), and C element (Figure f) in BN@F-SiC were analyzed by high-resolution spectroscopy.…”

A high-performance BN@F-SiC filler was prepared by depositing hydrophobic nano-SiC grafted by γ-aminopropyltriethoxysilane (KH550) and 1H,1H,2H,2H-trifluoro-noctyltriethoxysilane (FAS) on h-BN grafted by glycidoxy-propyltrimethoxysilane (KH560). A coating containing 1 wt % composite was prepared by dispersing the composite material in epoxy resin (EP), and dispersion, wear resistance, corrosion resistance, electrochemical analysis, and other tests were performed. Also, the influence of h-BN and SiC quality ratios on these properties was systematically studied. The results showed that the BN@F-SiC (2:1) composite material had the best dispersibility in EP. The water contact angle for the coating reached 118°, which indicated that the coating is hydrophobic. The friction coefficient for the BN@F-SiC (2:1)/EP coating was reduced by 89.68% compared with that for the coating without any filler. The potential dynamic polarization test and the salt spray test showed that BN@F-SiC had excellent corrosion inhibition performance. In addition, an EIS test showed that the impedance value for the BN@F-SiC (2:1)/EP coating exceeded 1010 Ω·cm2 at a frequency of 10–2 Hz (|Z|0.01Hz) after 400 h of soaking, which is nearly 103 times higher than that obtained for the EP coating without a filler. This research helps establish a foundation for future research investigating the development of wear-resistant hydrophobic and anticorrosive coatings.

“…Corrosion holes on coated steel substrates were also observed for coatings composed of a polymer-tryptamine conjugate after 6 h, [70] and for nanofibers composite coating after 9 h exposure to salt spray. [93] For anticorrosion thicker coatings (≈30-60 µm) [94][95][96][97] and/or with superhydrophobic property, [96,97] corrosion holes appeared later. Some thicker coatings reported in the literature displayed a better anticorrosion property, but did not possess the dual functionality of anticorrosion and antibiofouling.…”

Biofouling on surfaces immersed in aquatic environment induces catastrophic corrosion of metallic materials in petrochemical infrastructures, maritime facilities, and power plants. To combat the synergistic effect of biofouling and corrosion on the deterioration of metallic materials, smart coatings possessing a dual function of antibiofouling and anticorrosion properties are needed. Herein, redox‐responsive copolymer conjugates are synthesized and employed as coatings with the dual function of biofouling and corrosion mitigation. The dual function of copolymers is attributed to fluorinated units and the corrosion inhibitor 2‐mercaptobenzothiazole (MBT) conjugated via disulfide linkages. Indeed, the disulfide linkages can be cleaved in a reducing environment, yielding controlled release of the corrosion inhibitor MBT during corrosion process. The antibiofouling action against protein adsorption and algal attachment is enabled by cooperation of the repellent characteristic of fluorinated moieties and the biocidal effect of conjugated MBT.

“…In their experiments, the authors used ZnO nanoparticles and hydrophobic vapor-phase SiO 2 nanoparticles to build micro-/nano-structures that enhance the roughness of superhydrophobic surfaces, while 1H,1H,2H,2H-Perfluorodecyldichloromethylsilane (FAS) was used to modify the surface of the nanoparticles to present low surface energy. Zhang et al reported a method to modify the SiC surface from intrinsically hydrophilic to superhydrophobic nanoparticles using fluorinated organic substance FAS [ 40 ]. As shown in Figure 4 f, the alcohol hydroxyl group of the hydrolyzed FAS and the hydroxyl group on the SiC surface undergo a dehydration reaction to form Si-O-Si.…”

As research on superhydrophobic materials inspired by the self-cleaning and water-repellent properties of plants and animals in nature continues, the superhydrophobic preparation methods and the applications of superhydrophobic surfaces are widely reported. Silicones are preferred for the preparation of superhydrophobic materials because of their inherent hydrophobicity and strong processing ability. In the preparation of superhydrophobic materials, silicones can both form micro-/nano-structures with dehydration condensation and reduce the surface energy of the material surface because of their intrinsic hydrophobicity. The superhydrophobic layers of silicone substrates are characterized by simple and fast reactions, high-temperature resistance, UV resistance, and anti-aging. Although silicone superhydrophobic materials have the disadvantages of relatively low mechanical stability, this can be improved by the rational design of the material structure. Herein, we summarize the superhydrophobic surfaces made from silicone substrates, including the cross-linking processes of silicones through dehydration condensation and hydrosilation, and the surface hydrophobic modification by grafting hydrophobic silicones. The applications of silicone-based superhydrophobic surfaces have been introduced such as self-cleaning, corrosion resistance, oil–water separation, etc. This review article should provide an overview to the bioinspired superhydrophobic surfaces of silicone-based materials, and serve as inspiration for the development of polymer interfaces and colloid science.
