“…Due to its inherent hydrophobic properties, rice bran wax has the potential to serve as a plentiful and cost-effective bio-based filler, enhancing the protective capabilities of organic coatings. The low surface free energy of wax [55,56] can indeed be harnessed to enhance the hydrophobic properties of wood, as suggested by recent studies [57].…”

This work aims to highlight the multiple features shown by curcuma-based pigment and rice bran wax, which can be selectively employed as bio-based additives for the realization of multilayer wood coatings with multiple functionalities, harnessing the capabilities of the two environmentally friendly fillers, in line with current environmental sustainability trends. The role of the two green materials on the morphology of the composite layers was examined through observations employing scanning electron and optical microscopy, revealing a strong alteration of the film’s appearance, both its color and reflectivity. Additionally, their influence on the paint’s resilience was assessed by exposing the samples to UV-B radiation and consecutive thermal shocks. The coating displayed a clear and uniform change in color because of substantial curcuma powder photo-degradation but it remained exceptionally stable when subjected to thermal stresses. Moreover, the protective properties of the coatings were evaluated by conducting liquid resistance tests and water uptake tests, while the hardness and the abrasion resistance of the coatings were assessed to evaluate the effect of the additives on the mechanical properties of the coatings. In conclusion, this study showcases the promising joint action of curcuma-based pigment and rice bran wax in multilayer coatings. This combination offers vibrant yellow tones and an appealing appearance to the paint, enhances the surface’s water-repellent properties, and improves the mechanical resistance of the coatings.

“…Superhydrophobic wood coatings with environmental friendliness are becoming a mainstream direction for popular research [ 8 ]. Wax-based materials have been widely used as environmentally friendly materials for the preparation of superhydrophobic wood coatings [ 9 ]. Ideally, wood finishes should provide efficient protection from water while retaining the overall bio-based character of the material.…”

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.

“…The hydrophilicity of wood is due to the presence of hydroxyl-containing components in its composition. This leads to a change in the physical and mechanical properties of wood, a decrease in water resistance, dimensional stability, and contributes to its biological destruction under the influence of wood-destroying microorganisms (Meyer and Brischke, 2015;Ning et al, 2022;Zhenyu Wang et al, 2022).…”

Wood is a common natural polymeric material with hydrophilicity and low biostability with a limited service life. The article considers the issue of using a multicomponent composition (used motor oil, rosin, paraffin) for impregnating birch wood and giving it increased water resistance, bio-and dimensional stability. The possibility of recycling the used impregnated wood to obtain a biochar adsorbent was shown. The impregnating composition was characterized by the FTIR method to assess the possibility of interaction between the functional groups of the impregnating composition and wood. Moisture and water absorption decreased by more than 4 and 6 times. Volumetric swelling decreased by 57% relative to untreated wood, the effectiveness against swelling after 30 days was 46%. The high efficiency of the impregnating composition against the wood biodegradation has been established. The method of micro-X-ray tomography determined a high degree of filling of the anatomical structures of wood.
