WebMembranes with different contents of ion exchange resins were prepared. The presence of resins produces membranes with higher pore sizes and less permeabilities due to the porous substructure densification. In the case of the membrane with 20% resin content, a bimodal pore distribution was obtained with average pore radius of 2.50 and 8nm for ...
