WIPO Patent Application WO/2016/141550

Kind Code:

A1

Abstract:

An ion-exchange membrane is disclosed here that includes ion-permeable layers impregnated with an ion-exchange material and arranged in an order from one face of the membrane to the opposite face of the membrane such that opposing layers in the supporting membrane substrate provide sufficiently identical physical properties to substantially avoid irregular expansion when in a salt solution. The ion-permeable layers include at least one non-woven layer and at least one reinforcing layer.
