Abstract
The aerogel-type wood is prepared under crafts of dissolution of wood materials by 1 - propenyl -3- methylimidazolium ionic liquid and followed supercritical drying process. And then, cellulose fibers as supporting frame with incomplete three-dimensional cross-linked network are reformed after dissolution of aerogel-based timber. The reformed cellulose fibers possess microstructure that similar with light wood, stable chemical and physical properties, dry density of 0.221 g/cm3 and porosity over 87%. Additionally, the novel wood-based material achieved by green chemical treatment can continue to fix and store carbon absorbed during the growth stage of trees, and will also play a certain significance in areas of low-carbon and environmental protection.
