  • Gas separation membrane
    Patent number: 9724900
    Abstract: A method of fabricating a gas separation membrane includes providing a coextruded multilayer film that includes a first polymer layer formed of a first polymer material and a second polymer layer formed of a second polymer material, the first polymer material having a first gas permeability. The coextruded multilayer film is axially oriented such that the second polymer layer has a second gas permeability that is greater than the first gas permeability.
    Type: Grant
    Filed: December 15, 2014
    Date of Patent: August 8, 2017
    Assignees: Case Western Reserve University, The University of Texas at Austin
    Inventors: Eric Baer, Shannon Armstrong, Benny D. Freeman, Donald R. Paul, Grant Offord
