▎ 摘　　要

NOVELTY - Iron particles are adhered on a graphene substrate, and at least one shell is formed on the iron particles subsequent to the iron particles adhered to the graphene substrate. The one shell comprises silicon and suffer. USE - Formation of magnetic graphene composite used as electromagnetic wave and radio frequency absorber. Uses include but are not limited to airplanes, missiles, ships and reduction of detectability via radar. ADVANTAGE - The magnetic graphene composite is efficiently formed with excellent mobility and magnetic property, and improved resistivity without polluting the environment, and removes heavy metal e.g. chromium.
