N2 - This article reports dissolution, regeneration, and characterization of cellulose using an ionic liquid, namely 1-butyl-3-methylimidazolium chloride (BMIMCl). During dissolving process, BMIMCl takes much less time to dissolve cellulose with high degree of polymerization (DP = 4500) than other solvent system, lithium chloride/N,N-dimethylacetamide (LiCl/DMAc). Regenerated cellulose film from BMIMCl-cellulose solution is characterized by viscosity, thermo gravimetric analyzer, X-ray diffraction, pull test, and transmittance test. Compared with LiCl/DMAc-cellulose, BMIMCl-cellulose solution has lower viscosity and its film has lower Young's modulus and yield strength. From thermo gravimetric analyzer and X-ray diffraction experiment, BMIMCl-cellulose film has impurity and X-ray diffraction pattern similar with those of LiCl/DMAc-cellulose film. BMIMCl-cellulose film exhibits higher transmittance. The ionic liquid recovery test verifies that BMIMCl is highly recoverable with 99%, which proves that BMIMCl is a green solvent. Through the bending displacement test, the BMIMCl-cellulose film shows a good actuation behavior of electro-active paper.
