Abstract
This paper reports the studies on the properties of heterogeneous anion-exchange membranes prepared from polyvinyl chloride (PVC) as binder and anion-exchange resin powder. The effect of variation of ion-exchange resin particle size as well as the resin–binder ratio on different mechanical, electrochemical and morphological properties of the membranes have also been studied. It has been found that by using resins of suitable particle size and loading, it is possible to achieve heterogeneous membranes which are comparable with interpolymer membranes in performance. Moreover, heterogeneous membranes are found to have more dimensional stability than interpolymer membranes.
