Research progress on dissolution and functional modification of cellulose in ionic liquids

Ionic liquids with physico-chemical special characteristics such as the low melting point, adjustable acidity and good solubility have been used widely as the environment-friendly solvents; Cellulose are the most abundant natural renewable resources. Non-derivative cellulose solvents which being one category of ionic liquids have attracted enormous studies in cellulose recently. This review summarizes the dissolution and functional modification of cellulose as ionic liquids based on previous researches.
