Structure, Tensile and Electromechanical Properties of 1-Butyl-3-Methylimidazolium bis(trifluoromethylsulfonyl)imide Incorporated Cellulose

摘要

The effect of 1-butyl-3-methylimidazolium his (trifluoromethylsulfonyl) imide (BMITFSI) incorporation on the structure, tensile and electromechanical properties of cellulose was premeditated by scanning electron microscopy, X-ray diffraction, tensile test and bending actuation test. Both cellulose and BMITFSI were found to be thermodynamically compatible and have good miscibility. Addition of 0.02 wt% of BMITFSI resulted in augment of yield strength and Young's modulus; meanwhile they were decreased upon increasing the BMITFSI content. Upon dispersion of 0.1 wt% BMITFSI, the bending displacement of the cellulose actuator was drastically enhanced in comparison with that of cellulose membrane.
