  • Method for making a PVA-graphene film
    Patent number: 11479646
    Abstract: A process for making microwave-irradiated nanocomposites comprising graphene nanoplatelets dispersed in a polymer matrix, showing improved structural and electrical properties, is provided. The nanocomposites may be made using a solution casting technique, and may have a bilayer structure comprising a graphene-enriched layer in contact with a polymer-enriched layer. The nanocomposite may be used as a shielding material on electrical devices to decrease electromagnetic interference.
    Type: Grant
    Filed: February 25, 2020
    Date of Patent: October 25, 2022
    Assignee: King Fahd University of Petroleum and Minerals
    Inventors: Mamdouh Ahmad Al-Harthi, Hafiz Muhammad Afzal
