The impregnation with various nano particles of heat–treated woods

The aim of this study was to investigate to the effects of impregnation with nano sized titanium dioxide and boron nitride of heat-treated Beech (Fagus orientalis) and Oak (Quercus robur) wood. The impregnation process was applied to wood materials with using full-cell method in a chamber. After impregnation process, the samples were dried in the climate cabin at medium such as 65% Rh and 20°C during a month, and the densities at 0% and %12 moisture content (MC), water absorption and dimensional stability of the samples were determined according to the related standards. The results showed that the impregnation of wood with nano-fillers and heat treatment of wood decreased generally the water-wood relations and the heat treatment of wood materials have more an important factor to the decrease in water absorption and dimensional stability as compare with the impregnation of nano-fillers. The impregnation with TiO2 was also found to higher decrease the water absorption according the wood samples impregnated with nanoboron nitride.
