Electrical and electromechanical properties of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide-blended cellulose

摘要

The effect of 1-butyl-3-methylimidazolium bis (trifluoromethylsulfonyl)imide (BMITFSI) blending on the electromechanical and electrical properties of cellulose was premeditated by taking bending actuator test and electrical impedance analysis. Dispersion of BMITFSI in cellulose matrix was carried out by solution blending technique. Upon blending BMITFSI, bending displacement of the actuator was enhanced by eight times as compared to that of the pristine cellulose. Similar improvement in the AC conductivity of cellulose was observed. The effect of BMITFSI content and humidity on electromechanical and electrical properties of BMITFSI-loaded cellulose was discussed.
