Research on the Preparation of Wood-Based Composite Materials Using Wood Processing Residues

Abstract:

Cellulose is one of the most abundant renewable resources on the earth and could meet the increasing demand for environmental protection property and biocompatibility of materials. In recent years, ionic liquid, as a new type of environmentally-friendly medium and soft functional material, has gained widespread concern, for it has provided broad space for the further development of cellulose chemistry. This paper selects 1 - propenyl-3 - methylimidazolium ionic liquid to dissolve and reproduce the cellulose, thereby preparing the gel-type wood-based composite. The reformed fiber bundles constitute an unclosed three-dimensional cross-linked network as the support frame which owns the microstructure similar to balsa wood as well as the stable chemical and physical properties. Its oven dry density is 0.221 g/cm³ and the porosity is over 87%. This kind of gel-type wood-based composite prepared by the green chemical processing could fix and store the carbon adsorbed by trees, which is conductive for the environmental protection.
