Abstract

Effects of different reaction conditions such as temperature, time and amount of the added effervescent disintegrant on the porous structures of the porous polymer membranes prepared by microwave assisted effervescent disintegrable reaction between citric acid and sodium bicarbonate were investigated. Shorter reaction time at higher temperature is beneficial to higher porosity of the membrane. The ionic conductivity of the prepared porous polymer electrolytes based on the porous polymer membranes is up to 1.17×10-3S/cm and their electrochemical window is above 5V. This method is convenient and will greatly promote the practical application of porous polymer membranes in various areas.
