COMPOSITER SHEET FOR SHIELDING ELECTROMAGNETIC AND RADIATING HEAT INCLUDING GRAPHENE SHEET

摘要

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