“…Ou et al produced a superhydrophobic coating on the wood surface by one-step immersion in a composite silane solution, which provided the wood with excellent water/moisture repellency [ 5 ]. Cao et al constructed a transparent superhydrophobic coating by brushing a ZIF-8/HDTMS hybrid emulsion on the wood surface, which improved the stain resistance and durability of the wood’s surface [ 6 ].…”

As a renewable, environmentally friendly, natural, and organic material, wood has been receiving extensive attention from various industries. However, the hydrophilicity of wood significantly impacts the stability and durability of its products, which can be effectively addressed by constructing superhydrophobic coatings on the surface of wood. In this study, tung oil, carnauba wax, and silica nanoparticles were used to construct superhydrophobic coatings on hydrophilic wood surfaces by a facile two-step dip-coating method. The surface wettability and morphology of the coatings were analyzed by a contact angle meter and scanning electron microscope, respectively. The results suggest that the coating has a micron–nanosized two-tiered structure, and the contact angle of the coating is higher than 150° and the roll-off angle is lower than 10°. Sandpaper abrasion tests and UV diffuse reflectance spectra indicate that the coatings have excellent abrasion resistance and good transparency. In addition, the coated wood shows excellent self-cleaning and water resistance, which have great potential for applications in industry and furniture manufacturing.

“…Cao et al fabricated superhydrophobic wood coating using a single-step technique with SCA 150°. The coating withstands 10 cycles of abrasion with a 50 g weight . From literature studies, the combination of nanoparticle with the polymer matrix for the superhydrophobic surface has less mechanical durability due to the poor compatibility at the interphase of the polymer-nano system.…”

A superhydrophobic approach free from toxic nanoparticles and silane-and fluorine-based compounds is the need of the hour in order to develop ecofriendly and sustainable materials for multifunctional applications. The extremely hygroscopic nature of the wood reduces its service life, which can be addressed with a renewable sourced polymeric coating to explore the wide use and enhanced durability. The current work describes the catalyst-free modification of CNSL (cashew nut shell liquid)-sourced cardanol diol with saturated fatty acids of varying carbon number (C16−C18). The esterification was carried out using palmitic acid and stearic acid in different stoichiometries to form prepolymers and characterized through FTIR, 1 H NMR, and 13 C NMR. In addition, curing behavior, thermal degradation profile, lap shear strength, and hydrophobicity of both samples were studied and subsequently optimized for further studies. Stearic acid-modified cardanol prepolymer (Sa-Cd) coating showed higher superhydrophobicity on soft wood and hard wood substrates with water contact angles of 153−156°and hysteresis 3−7°. SEM, OSP, and SPM analyses were carried out to understand the superhydrophobic feature attributed to the synergistic effect of inherent roughness of wood and chemical functionality of polymers. The coated substrates displayed excellent self-cleaning properties along with anti-icing and oil in water removal. Also, the coated substrates retained superhydrophobicity against water, corrosive chemicals, heat, and abrasion (100 cycles). The developed green materials offer a superhydrophobic functional coating for wood in order to widen its applications.
