▎ 摘  要

NOVELTY - The film has a base film (1) which is bonded with a first graphene layer (2). An upper side of the first graphene layer is thermally compressed with a stabilizing layer (4). A copper wire mesh (3) is embedded in the stabilizing layer. Several reflective particles (5) are bonded on the upper side of the stabilizing layer. An adhesive layer (6) is provided on the outside of the reflective particles. A second graphene layer (7) is connected to one side of the adhesive layer. A protective layer (8) is connected to the upper side of the second graphene layer. USE - High-frequency electromagnetic wave absorption film with high thermal conductivity for shielding electromagnetic waves. ADVANTAGE - The absorbent film can be produced at one time, reducing multiple transfers or other steps, increasing production efficiency, reducing production costs, and increasing production capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production device of high-frequency electromagnetic wave absorbing film with high thermal conductivity. DESCRIPTION OF DRAWING(S) - The drawing shows a structure schematic diagram of a high-frequency electromagnetic wave absorption film.
