Effect of Nano-ZnO on Decay Resistance and Artificial Weathering of Wood Polymer Composite

Effect of Nano-ZnO on Decay Resistance and Artificial Weathering of Wood Polymer Composite

Wood polymer nanocomposite (WPNC) was prepared by impregnation of styrene and Nano zinc oxide into poplar wood (Populus deltoids Marsh.). WPNCs containing different loading of nano zinc oxide, namely 0, 0.5, 1 and 1.5 percent (by weight of monomer), were made. Then the effect of addition of nanoparticles on the decay resistance and artificial weathering were studied. The WPNCs were subsequently exposed to the artificial weathering test with duration of 200, 400 and 800 hours and decay test according to a modified ASTM D1413 standard. The results showed that the amount of color change of samples treated with nano zinc oxide was less than untreated one, also the decay resistance of the composite against the fungi with increasing of concentration was improved.
