“…AKD-modified wood exhibits a high degree of hydrophobicity, as well as excellent resistance to water, acids, and toluene, and self-cleaning effects. Yang et al [ 33 ] constructed micro/nanostructures using PDA and alumina nanoparticles (Al 2 O 3 ). The superhydrophobic wood was prepared through grafting low surface energy to the wood surface modified by octadecyltrimethoxychlorosilane The superhydrophobic wood surfaces exhibited excellent resistance to flow scouring, acid and alkali corrosion, and organic solvents, providing excellent stability in the face of environmental challenges.…”

Superhydrophobic substances were favored in wood protection. Superhydrophobic treatment of wood is of great significance for improving the service life of wood and expanding its application fields, such as improving dimensional stability, durability, UV stability, and reducing wetting. The superhydrophobic phenomenon is attributed to the interaction of micro/nano hierarchical structure and low surface energy substances of the wood surface. This is the common method for obtaining superhydrophobic wood. The article introduces the common preparation methods of superhydrophobic wood material coatings and their mechanisms. These techniques include lithography, sol–gel methods, graft copolymerization, chemical vapor deposition, etc. The latest research progress of superhydrophobic wood material coatings application at domestic and overseas is reviewed, and the current status of superhydrophobic coating application in wood materials and construction is summarized. Finally, superhydrophobic on wood in the field of applied research is presented, and the development trend in the field of functional improvement of wood is foreseen.

“…Yang et al [ 88 ] believed that the introduction of chemical bonds was an important way to improve the superhydrophobic durability of a wood surface. The strong viscosity of polydopamine was applied as the bottom layer, and nano-Al 2 O 3 was used to prepare a micro-nano rough structure.…”

Wood-based materials are multifunctional green and environmentally friendly natural construction materials, and are widely used in decorative building materials. For this reason, a lot of research has been carried out to develop new and innovative wood surface improvements and make wood more appealing through features such as fire-retardancy, hydrophobicity, and antibacterial properties. To improve the performance of wood, more and more attention is being paid to the functioning of the surface. Understanding and mastering technology to improve the surface functionality of wood opens up new possibilities for developing multifunctional and high-performance materials. Examples of these techniques are ion crosslinking modification and coating modification. Researchers have been trying to make wooden surfaces more practical for the past century. This study has gradually gained popularity in the field of wood material science over the last 10 years. This paper provides an experimental reference for research on wood surface functionalization and summarizes the most current advancements in hydrophobic, antibacterial, and flame-retardant research on wood surfaces.

“…For instance, some studies revealed that the addition of various nanoparticles, such as TiO 2 [23], ZnO [24], SiO 2 [25], and CeO 2 [26], has enhanced the UV light resistance of wood coatings. On the other hand, nanoparticles with high hardness, stiffness, and thermal stability, such as nanosilica [27], nanoalumina [28], nanoclay [29], and nanocellulose [30], can be used to increase the mechanical properties and water repellency of wood coatings [31]. Moreover, with the application of nanomaterials such as copper nanopowders [32], nanotitanium [33], and silver [34,35], wood paint can gain significant antibacterial properties.…”

This work aims to reveal the effect of a high amount of cellulose fibers on the durability and protective behavior of a bio-based wood paint. The influence of the filler on the morphology of the coatings was investigated by scanning electron microscopy observations, while the durability of the paint was evaluated by exposing the samples to UV-B radiation and continuous thermal shocks. Infrared spectroscopy analysis, colorimetric inspections, adhesion tests and scanning electron microscope observations were employed to assess the role of the high concentrations of fillers in affecting the resilience of the acrylic matrix. Moreover, the impact of the filler on the barrier performance of the coatings was estimated using a liquid resistance test and a water uptake test. Finally, the mechanical properties of hardness and abrasion resistance of the layers were evaluated by means of the Buchholz Hardness Indentation test and the Scrub test. Ultimately, this study demonstrates the pros and cons of using large amounts of cellulose fibers as filler in wood paint: the work warns against the excessive use of these fibers, which need a threshold limit so as not to significantly change the coating’s structure and thereby weaken its protective properties.
