On the Application of Green Ionic Liquids in the Preparation Process of the Gel-Type Wood Composites Materials

Abstract:

Due to the excellent physical and chemical properties of low melting point, high stability, low vapor pressure, and adjustable solubility, the ionic liquid is widely used in the dissolution of cellulose, regeneration and applied research. This thesis selects the ionic liquid to dissolve the wooden ponder in the processed wood residues and observes its dissolution behavior including the dissolution process of the cellulose in the ionic liquid and the cellulose dissolution as well as its regeneration mechanism. It turns out that the chemical structure of successfully prepared gel-type wood composite material does not changes and its microstructure retains a complete timber microscopic structure. For the fiber bundle formed after the celluloses dissolution, one part functions as the support skeleton, another forms a closed three-dimensional crosslinked network, which possesses stable chemical and physical properties. The gel-type wood composites owns suitable visual characteristics, which can render the "natural", "comfortable", "simple and elegant", and "crisp" visual psychological impression.
