Distribution of Nano Particles in the Wood Impregnated with Nano Scale Boron Nitride

Abstract

Thermal stability is the one of the most important properties of wood and wood based materials. Many papers have been done to rise the thermal stability. Nanotechnology offers an important opportunity to improve the thermal stability that cannot be obtained with previous techniques. Homogenously distribution of nano fillers on the surface of the wood can provide an improvement on the thermal stability of wood. In this study, wood was impregnated with nano-sized boron nitride (BN) with a solution of 3% in a vessel which can be controlled the ratio of vacuum and pressure. SEM/EDX analysis of the impregnated samples was conducted to determine the distribution of nano particles. SEM images showed that some deposits of BN on the pits and the cell wall were found, but the BN deposits were only viewed until 10 mm deeply (samples are 30 mm thickness) under the surface.
