| Outline of Final Research Achievements |
Heat-treated wood has desired properties such as high dimensional stability and increased resistance to biodegradation. This study investigated a new heat treatment process using supercritical carbon dioxide. We prepared sugi heartwood specimens. The specimens were heated in supercritical carbon dioxide and measured the anti-swelling efficiency that indicates the dimentional stability against the moisture. As a result, it was shown that high dimensional stability was obtained in a short treatment time using supercritical carbon dioxide. From the component analysis of specimens, it was suggested that the moisture in specimen accelerate the thermolysis of the wood components, especially hemicellulose, leading to a decrease in adsorption sites.
