capacity (IEC), electrical resistance, permselectivity, sorption isotherms and methanol permeability give information on conductive and methanol permeability properties. These methods have been applied on blends of polyethersulfone (PES)/sulfonated polysulfone (SPSf ) and PES/ sulfonated polyetheretherketone (SPEEK) with composition changed to give defined properties.
