▎ 摘　　要

NOVELTY - A graphene-based composite wave-absorbing material is obtained by loading silicon dioxide-coated carbonyl iron core-shell composite particles on a graphene sheet. USE - Graphene-based composite wave-absorbing material (claimed). ADVANTAGE - The graphene-based composite wave-absorbing material having excellent wave absorption characteristics at different frequencies, and low density, is manufactured efficiently by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of graphene-based composite wave-absorbing material, which involves dispersing graphite oxide in silicon dioxide-coated carbonyl iron core-shell composite particle dispersion, and ultrasonically reducing the graphite oxide.
