Achieving Sustainable Wood Preservation Using Nanomaterials

In this study, a cost-effective and energy-efficient approach was used to impregnate the surface of solid wood with three different nanoparticle solutions and a hydrophobic polymer solution for wood protection. Impregnation of Ch, ZnO and SnO2 nanoparticles increased the thermal stability of lignocellulosic materials, resulting in weight losses of 75.7-80.5% between 339-387°C. The binding of nanoparticles through impregnation also increased the water uptake rate, while silanization with HP increased hydrophobicity by 22.9-26.2%. The resulting wood was evaluated in terms of durability and performance as well as water and fire resistance, and it was predicted that it could be a sustainable approach to minimize the effects of adverse weather conditions on wood materials while reducing negative impacts on the environment and human health.
