  • Multi-layer graphene-metal-polymer sheet for shielding electromagnetic wave
    Patent number: 10306818
    Abstract: The present invention relates to a multi-layer graphene-metal-polymer sheet for shielding electromagnetic wave, wherein an electromagnetic wave shielding effect is able to be increased by using graphene-metal nanocomposite powder in which graphene and metal particles are bonded as a conductive material and by constituting a multi-layer structure instead of increasing a content of the graphene-metal nanocomposite powder.
    Type: Grant
    Filed: April 14, 2017
    Date of Patent: May 28, 2019
    Assignees: LG Chem, Ltd., Korea Advanced Institute Of Science And Technology
    Inventors: Soon Hyung Hong, Ho Jin Ryu, Jae Young Oh, Hye Ji Im
