摘要:
In this contribution, we report a new type of poly (ionic liquids) prepared by imidazolium ionic liquids directly grafting onto polyethylene oxide backbone. Different molecular weights of poly (ionic liquids) are obtained with a low glass transition temperature up to -14 degrees C. The materials as polymer electrolyte achieve a high conductivity around 10 (-5) S cm(-1) at 30 degrees C and close to 10(-3) S cm(-1) at 90 degrees C. High viscosity up to 4000 Pa s at room temperature would minimize the electrolytes leaking in electrochemical devices. (C) 2014 Wiley Periodicals, Inc.
