  • Catalytic composite
    Patent number: 11668222
    Abstract: A catalytic composite is formed of a catalytic layered assembly including a porous catalytic fluoropolymer film and one or more felt batts connected with the porous catalytic fluoropolymer film. At least one felt batt is positioned adjacent the upstream side of the porous catalytic fluoropolymer film to form the catalytic composite. The fluoropolymer film is perforated to allow for enhanced airflow therethrough while retaining the capability of catalyzing the reduction or removal of chemical species in fluid flowing through the catalytic composite.
    Type: Grant
    Filed: July 2, 2021
    Date of Patent: June 6, 2023
    Assignee: W. L. Gore & Associates, Inc.
    Inventors: Robert Eves, Tarun Poddar, John A. Tomanovich
