Cellulose is an inexhaustible and unlimited supply of renewable organic resources in nature. Through photosynthesis it can produce 100 billion tons of cellulose every year, they are widely used to develop textile fiber materials. Cellulose molecules have many hydrogen bonds, complex aggregation structure and high crystallinity, which make the attainability of the solvent to cellulose low so it is difficult to be dissolved in common solvents. It limits cellulose's further development, so it is particularly i...
