Preparation and Performance of Crosslinked Proton Exchange Membranes Containing Carboxyl Group
Abstract:
Excessive water swelling has been an important problem for proton exchange membranes materials,especially for sulfonated poly aryl ether ketone.In this article,a sulfonated polymer containing ester group was hydrolyzed to yield carboxylic side group on its side chain,then the polymer was blended with polyvinyl alcohol and heat-treated to obtain crosslinked blend membranes.The results showed that Tg of the crosslinked membrane was increased significantly suggesting the presence of crosslinking reaction in the polymers.At 100℃,the proton conductivity,water uptake and swelling ratio of the crosslinked membranes are in the ranges of 0.072~0.065 S/cm,51%~89%,and 19%~30%,respectively.Both the water uptake and swelling rate of the membrane decreased in a certain degree.This method is promising for the preparation of sulfonated poly arylene ether based proton exchange membrane with improved overall performance.
