Preparation of porous polymer electrolyte by a microwave assisted effervescent disintegrable reaction

Porous polymer membranes with sub-micrometer pores were successfully prepared by a novel microwave assisted effervescent disintegrable reaction. The fine connected porous structure was obtained by promoting effervescent disintegrable reaction between citric acid and sodium bicarbonate due to the assistance of microwave. The ionic conductivity of the prepared gelled polymer electrolyte is up to 1.17 × 10−3 S cm−1 and electrochemical window 4.5 V. This method provides a convenient route to prepare porous polymer electrolyte, which will greatly promote the practical application of porous polymer electrolytes.
