Abstract
Recently, the use of nanoparticles UV-absorber to protect the artworks of cellulosic and lignocellulosic has a special place. In this study, white poplar wood samples treated with dispersions of Nano-Tio2 and Nano-ZnO at two doses of 1% and 2% was investigated. The samples were placed under accelerated aging of UV-B irradiation. Structural changes were investigated by application of spectro-colorimeter and ATR-FTIR spectroscopy. Results showed that 1% of Nano-TiO2 little ability to protect from UV-irradiation. increasing the dose of nanoparticles increases the crystallinity index and amorphous cellulose degradation in the area. Treated with Nano-ZnO reduced degradation of lignin and polysaccharides in wood, and increasing the dose of nanoparticles added ability to protect against UV-irradiation. Increase of the both nanoparticles caused reduction of the darkens and the total colour difference (DE*). Treated samples with Nano-ZnO had total colour difference less than the titanium dioxide. Generally, zinc oxide nanoparticles have better ability of titanium dioxide to protection of wood against UV irradiation.
