Abstract
This study was carried out to investigate the distribution and penetration of PEG molecules into the cell wall of wood by SEM-EDS method. SEM observation indicated that the cell walls of PEG-treated specimen were swollen, and didn't show any change in their shapes, while the cells of untreated specimen were more or less collapsed. The results of X-ray analyses of potassium stained samples revealed the distribution of the impregnated chemicals within the cell walls, when considering the distribution of potassium ions in the cell walls. Consequently, this study supported the possibility of PEG molecules penetrated into the wood cell wall play an important role in enhancing the dimensional stability of wood.
