The morphology of polyacrylonitrile composite membranes containing microdispersions of ion exchange resins was investigated by gas adsorption, mercury porosimetry, and scanning and transmission electron microscopy. The relation between the structure, hydration and permeability of composite membranes at the transmembrane difference of pH and pNa was studied.
