Solubility of cellulose in ionic liquid and its viscoelasticity

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Cellulose is insoluble in both water and general organic solvents. Recently, it was reported that cellulose is soluble in certain kind of ionic liquids, which are non-volatile liquid phase organic salts at around room temperature. In this study, we report on the difference of the viscoelastic properties of cellulose solutions prepared by two different methods. The effects of the added salt (LiCl) on the dissolution of cellulose are also examined. It was concluded that cellulose can be uniformly dissolved in the ionic liquid when samples are prepared by addition of LiCl or keeping under reduced pressure at 130°C.
