▎ 摘　　要

NOVELTY - The multi-layer graphene-metal-polymer sheet has multiple graphene-metal-polymer sheets, where sheets are stacked in form of multi-layer graphene-metal-polymer sheet. The graphene-metal-polymer sheet includes graphene-metal nanocomposite powder and polymer material. The graphene-metal nanocomposite powder includes graphene bonded to metal nanoparticles. The contents of graphene-metal nanocomposite powder, relative to total weight of graphene-metal-polymer sheet are different in adjacent graphene-metal-polymer sheets in multi-layer graphene-metal-polymer sheet. USE - Multi-layer graphene-metal-polymer sheet for shielding electromagnetic wave. ADVANTAGE - A single layer including a polymer and a conductive material can be constituted as multiple layers, thus improving the electromagnetic wave shielding effect without increasing the content of the conductive material. The multi-layer graphene-metal-polymer sheet for shielding electromagnetic wave can increase an electromagnetic wave shielding effect by using the graphene-metal nanocomposite powder as the conductive material and by constituting a multi-layer structure instead of increasing a content of the graphene-metal nanocomposite powder. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view of an electromagnetic wave shielding effect.
