Special Issue Information

Dear Colleagues,

In the realm of the wood processing industry, the demand for high-performance, durable, and multi-functional wood products has been steadily on the rise. Wood, being a natural and widely used material, has its own set of limitations, such as vulnerability to environmental factors like moisture, heat, and pests, as well as the risk of surface degradation over time.

Functional coatings have emerged as a crucial solution to enhance the properties of wood. These coatings not only provide protection against various forms of damage, but also endow wood with additional functions. For example, some coatings can improve the fire resistance of wood, reducing the risk of fire-related disasters. Others can enhance the antibacterial properties, which is particularly important in applications where hygiene is a concern, such as in kitchens and hospitals.

The research on innovations in functional coatings for wood processing is of great significance. It not only addresses the existing challenges in the wood industry but also paves the way for the development of new, more sustainable, and high-value-added wood products. By continuously exploring and innovating in this area, we can expand the application scope of wood, making it more competitive in the global market and promoting the sustainable development of the entire wood processing industry.

The aim of this Special Issue is to comprehensively showcase the latest advancements, research findings, and innovative ideas in the field of functional coatings for wood processing. It aims to bring together contributions from researchers, scientists, and industry professionals to present a holistic view of the current state of the art. By doing so, the Special Issue intends to stimulate further research and development in this area, foster collaboration between different stakeholders, and ultimately drive the progress of the wood processing industry. Additionally, it seeks to identify potential gaps in the existing knowledge and suggest future research directions that can lead to even more effective and sustainable functional coatings for wood.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: environmentally friendly coatings, functional coatings, and decorative coatings for wood and wood products processing.

We look forward to receiving your contributions.

Antibacterial microcapsules were prepared by using a compound of chitosan with an antioxidant of bamboo leaves (AOB) as the wall material and tung oil as the core material. The microcapsules were modified by adding them to waterborne coatings, and the modified waterborne coatings were coated onto Basswood samples. The performance of the obtained coatings was then characterised through a comparative analysis. The investigation focused on the effect of varying percentages of chitosan and AOB in microcapsules with a constant core-to-wall ratio on the performance of the waterborne on the surface of Basswood. The core-to-wall ratio of the microcapsules was established at 1:2, with the ratios of chitosan and AOB in the walls fixed at 9:1, 8:2, and 7:3, respectively. The results demonstrated that the gloss, impact resistance, and hardness of the coatings exhibited an increase with increasing ratios of AOB under varying Mchitosan:MAOB (MC:MA) conditions. Conversely, the adhesion exhibited a decrease with an increase in AOB. The colour difference value exhibited minimal change. The self-healing rate of the coating exhibited an initial increase, followed by a subsequent decrease, in response to the increasing AOB concentration. The antimicrobial effect was optimised at a ratio of 9:1 for the combination of chitosan and AOB. The coating of Basswood containing 1.0% microcapsules and 9:1 MC:MA demonstrated superior performance, exhibiting a gloss of 9.7 GU, a colour difference ΔE of 31.03, a hardness of HB, an adhesion rating of grade 1, an impact resistance of grade 4, a self-healing rate of 19.09%, and a noteworthy antimicrobial effect against both Escherichia coli and Staphylococcus aureus.

This work investigates the relationship between the material properties of wardrobe furniture and visual and tactile emotional responses, with a focus on age-related differences in emotional experiences. This research measured material surface properties (roughness, gloss, and Lab color) and utilized the PAD (pleasure, arousal, dominance) emotion model to assess emotional responses among elderly and younger participants. (1) In the context of tactile emotional experiences, a systematic correlation was observed between surface roughness and the reported levels of pleasure, arousal, and dominance in both elderly and younger participants. Moreover, pleasure demonstrated a systematic correlation with gloss. Rough surfaces were perceived as unpleasant. The elderly participants showed greater emotional dominance when exposed to rough surfaces. (2) In terms of visual–tactile emotional experiences, a responsive relationship was found between pleasure, dominance, and the a* parameter (representing the red and green color channels) in both age groups. However, no systematic correlations were observed between luminance (L*), glossiness, and PAD emotional experiences in either group. A responsive correlation was found between pleasure, dominance, and the b* parameter (representing the yellow and blue color channels) in elderly individuals. Notably, a significant correlation was observed between arousal and roughness in younger individuals. These findings suggest a partial difference in emotional responses across the PAD dimensions between elderly and younger participants. Full article
