  • Enhancing performance of perfluorinated ionomer membranes via dopant incorporation, method of making thereof and the membrane
    Patent number: 5417832
    Abstract: The present invention describes a perfluorinated ionomer membrane having a improved transport characteristics. A surfactant species is added to a polymer mixture prior to film casting. The resulting membranes have a measurably altered membrane microstructure and improved transport characteristics over prior art membranes. The present invention describes the method of producing the improved membranes. The membranes of the present invention are useful in a number of separation processes, including the separation of NH.sub.3 from gaseous and liquid mixtures, in the production of NaOH and Cl.sub.2 gas from the electrolytic dissolution of NaCl, in the separation of toxic and radioactive metals from aqueous streams, and in solid polymer electrolyte H.sub.2 /O.sub.2 fuel cells.
