Abstract
The invention is directed a synthetic wood composite comprising biomimetic macromolecules and methods for the preparation thereof.
Claims34
A composite comprising lignin, cellulose and hemicellulose, wherein the cellulose content is about 40 to about 60% (w/w), the hemicellulose content is about 20 to about 40% (w/w), and the lignin content is about 10 to about 30% (w/w), wherein the lignin is selected from a kraft lignin or a lignosulfonate, wherein the hemicellulose is xylan, and wherein the composite is transparent.
A method of preparing a composite comprising lignin, cellulose and hemicellulose, wherein the cellulose content is about 40 to about 60% (w/w), the hemicellulose content is about 20 to about 40% (w/w), and the lignin content is about 10 to about 30% (w/w), wherein the lignin is selected from a kraft lignin or a lignosulfonate, wherein the hemicellulose is xvlan, and wherein the composite is transparent;
- comprising the steps of:
- a. dissolving the lignin and additional component in an ionic liquid to obtain a solution;
- b. applying the solution to a surface and obtaining a hydrogel;
- and
- c. drying the hydrogel to obtain the composite.
