Summary
Thermal modification is a process which improves the properties of wood, resulting in a material that can be disposed at the end of the product life cycle without presenting an environmental hazard. Thermally modified wood retains as a natural product and the grain, original colour variances and characteristics of wood are still present. However, exposure to daylight causes brightening or graying of heat treated wood surfaces. In ordar to tackle this challenge we are proposing a novel way to improve the UV stability of thermally modified wood using nano based stabilizers. But instead of coating nanoparticles on heat treated wood, wood surfaces will be treated with nanoparticle (ZnO or CeO2) solutions, thereby forming protective envelope on a wooden surface, which will be further heat treated under controlled temperature and time. This technique induces a chemical bonding between the wood and nanomaterial thus protecting chromophoric groups from UV light degradation.
