COMPOSITER SHEET FOR SHIELDING ELECTROMAGNETIC AND RADIATING HEAT INCLUDING GRAPHENE SHEET

摘要

The present invention is a composite for heat radiation and shielding, characterized in that it comprises a first layer formed of a metal and a second layer formed on one surface of one surface of the first layer and including charged chemically modified graphene and graphene flakes. As a sheet, it has the advantage of improving the thermal conductivity and shielding ability of electromagnetic waves while securing economic efficiency by using a second layer including charged chemically modified graphene and graphene flakes.
