As the focus of architecture, furniture, and other fields, wood has attracted extensive attention for its many advantages, such as environmental friendliness and excellent mechanical properties. Inspired by the wetting model of natural lotus leaves, researchers prepared superhydrophobic coatings with strong mechanical properties and good durability on the modified wood surface. The prepared superhydrophobic coating has achieved functions such as oil-water separation and self-cleaning. At present, some methods such as the sol-gel method, the etching method, graft copolymerization, and the layer-by-layer self-assembly method can be used to prepare superhydrophobic surfaces, which are widely used in biology, the textile industry, national defense, the military industry, and many other fields. However, most methods for preparing superhydrophobic coatings on wood surfaces are limited by reaction conditions and process control, with low coating preparation efficiency and insufficiently fine nanostructures. The sol-gel process is suitable for large-scale industrial production due to its simple preparation method, easy process control, and low cost. In this paper, the research progress on wood superhydrophobic coatings is summarized. Taking the sol-gel method with silicide as an example, the preparation methods of superhydrophobic coatings on wood surfaces under different acid-base catalysis processes are discussed in detail. The latest progress in the preparation of superhydrophobic coatings by the sol-gel method at home and abroad is reviewed, and the future development of superhydrophobic surfaces is prospected.

“…[ 21 ] Moreover, carbon‐based materials are regarded as one of the most promising photothermal materials because they are widely found in nature, nontoxic, and at low cost. [ 22 ] Among them, graphene has been widely studied. This is because of the graphene's internal multilayer‐stacked structure.…”

Fresh water resources can be sustainably harvested through interfacial evaporation by solar energy. To enhance the efficiency of solar interfacial evaporation, a metal graphene alcohol gel was synthesized using a one‐step thermal reduction technique. Subsequently, a metal graphene aerogel was produced using freeze‐drying technology. The hydrothermal treatment method was applied to introduce asymmetric moisture and roughness on the upper and lower surfaces of the aerogel. The unique structure of the aerogel plays a significant role in facilitating continuous water transport to the interface for evaporation. The top layer, being hydrophobic, and the bottom layer, being hydrophilic, contribute to this process. Importantly, the top layer’s design ensures that an excessively thick water film does not form, thereby preventing any adverse effects on light absorption efficiency. The aerogel exhibits an outstanding water evaporation rate (WER) is 1.75 kg·m‐2·h‐1 and a remarkable photothermal conversion efficiency (PTCE) is 93.17% under one solar radiation intensity. This is because the aerogel has a unique three‐dimensional structure. This special three‐dimensional structure has an interconnected microporous‐like appearance inside, which increases the evaporation area. Metal‐graphene aerogel is based on the electric field dielectric evaporation mechanism of metal nanoparticles localized surface plasmon resonance (LSPR) effect and the thermal mediated evaporation mechanism of graphene full spectrum. Under the double action, the photothermal conversion efficiency has been significantly improved. Our meticulously created metallic graphene aerogel performs exceptionally well at evaporating water. As a result, it presents a promising and practical avenue for exploring effective solar interfacial evaporation.This article is protected by copyright. All rights reserved.
