  • USE OF GRAPHENE-POLYMER COMPOSITES TO IMPROVE BARRIER RESISTANCE OF POLYMERS TO LIQUID AND GAS PERMEANTS
    Publication number: 20230039392
    Abstract: A packaging material comprising a graphene-reinforced polymer matrix composite (G-PMC) is disclosed. The packaging material has improved barrier resistance to gas and liquid permeants. Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.
    Type: Application
    Filed: August 29, 2022
    Publication date: February 9, 2023
    Applicant: Rutgers, The State University of New Jersey
    Inventors: Jennifer K. Lynch-Branzoi, Thomas J. Nosker, Bernard H. Kear, Charles T. Chang
