Special Issue Information

Dear Colleagues,

In recent decades, wood and wood-based composites have garnered extensive attention due to their renewable, sustainable, and eco-friendly properties. With a growing global demand for sustainable development and green building materials, new technologies and approaches for utilizing these natural resources have become a focal point in both scientific research and the industry. This Special Issue, “Wood and Wood-Based Composites: New Frontiers in Modification, Performance, and Sustainability”, aims to compile and showcase the latest research findings on modification techniques and emerging applications of wood and its composites.

This Special Issue will explore physical, chemical, and biological methods for modifying wood and wood-based composites and how these modifications can enhance the materials’ performance, durability, and functionality. We are particularly interested in innovative techniques that improve the materials’ resistance to microbes, fire, water, and mechanical forces. Additionally, this Special Issue will delve into the applications of these materials in construction, furniture, packaging, the automotive industry, and beyond, as well as how they contribute to sustainable and eco-friendly advancements in these areas. Authors are welcome to submit their latest research on this topic in the form of original research or review articles.

High-temperature vapour-phase acetylation (HTVPA) is a simultaneous acetylation and heat treatment process for wood modification. This study was the first investigation into the impact of HTVPA treatment on the resistance of wood to biological degradation. In the termite resistance test, untreated wood exhibited a mass loss (MLt) of 20.3%, while HTVPA-modified wood showed a reduced MLt of 6.6–3.2%, which decreased with an increase in weight percent gain (WPG), and the termite mortality reached 95–100%. Furthermore, after a 12-week decay resistance test against brown-rot fungi (Laetiporus sulfureus and Fomitopsis pinicola), untreated wood exhibited mass loss (MLd) values of 39.6% and 54.5%, respectively, while HTVPA-modified wood exhibited MLd values of 0.2–0.9% and −0.2–0.3%, respectively, with no significant influence from WPG. Similar results were observed in decay resistance tests against white-rot fungi (Lenzites betulina and Trametes versicolor). The results of this study demonstrated that HTVPA treatment not only effectively enhanced the decay resistance of wood but also offered superior enhancement relative to separate heat treatment or acetylation processes. In addition, all the HTVPA-modified wood specimens prepared in this study met the requirements of the CNS 6717 wood preservative standard, with an MLd of less than 3% for decay-resistant materials.
