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.
