Graphenemagnetic metal composite for absorbing electromagnetic wave and the preparation method thereof

摘要

The present invention relates to a graphene-magnetic metal composite for electromagnetic wave absorption and a method of manufacturing the same. More particularly, the present invention relates to a graphene-magnetic metal composite having a structure in which plate-like crystalline magnetic metal particles are bonded to the surface of reduced graphene oxide (RGO) Magnetic metal complex and a method of manufacturing the same. The graphene-magnetic metal composite for electromagnetic wave absorption according to the present invention can maintain the magnetic permeability at a wide broad band from low to high frequency by bonding magnetic metal particles having a nanoscale plate structure on the reduced graphene oxide surface. Since the permittivity can be controlled through hybridization with the pin, it has an effect of exhibiting excellent electromagnetic wave absorbing ability.
