▎ 摘　　要

NOVELTY - The composite material (1000) has a porous graphene structure (GS) that is comprised of graphene membrane (GL) and pores surrounded by the graphene membrane. An organic polymer layer (OL) is provided for covering the porous graphene structure. The magnetic material particles (MP) are provided between the porous graphene structure and the organic polymer layer and selectively provided on the graphene film. USE - Composite material for electromagnetic wave shielding. ADVANTAGE - The composite material can effectively block electromagnetic waves. The composite material for shielding electromagnetic wave can be used in electronic components having various shapes because of the flexibility. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the composite material for electromagnetic wave shielding.
