Abstract
Weathering of wood surfaces remains a major problem when timber is used in exterior exposures. Surface degradation starts almost immediately, mainly induced by ultraviolet light (UV). This surface deterioration often leads to a series of physical, microscopic, and chemical changes that cause dramatic declines in surface appearance. Although traditional surface protection systems can limit UV degradation, all existing surface treatments have drawbacks. Opaque coatings such as paint totally mask the natural appearance of wood, which is not desirable when the purpose of treatment is to maintain the natural wood appearance. Less robust clear coatings often provide only 12 to 24 months of protection and must be reapplied to provide continued protection. The desire to prolong wood performance in exterior applications has created continuing interest in developing more effective additives and treatments to reduce wood weathering. One alternative approach to wood surface modification for UV protection is the use of nanotechnology. Nano-particles have unique properties that may have promise for surface protection, but our understanding of the mechanisms by which these materials perform remains limited. This study was performed using only nano-particles to simplify the experiments and help delineate the direct role of the nano-particles. The characteristics of nano-particles in relation to wood protection against UV light were explored. The most effective nano-particles were conducted to evaluate the nano-particle/wood interactions.
