▎ 摘  要

NOVELTY - The utility model claims an electromagnetic shielding film with graphene-nano silver composite layer, belonging to the technical field of shielding film; it comprises a base layer, the base layer is orderly provided with a graphene-nano silver composite layer and a hardened layer, wherein the graphene-nano silver composite layer is obtained by mixing graphene slurry and nano silver slurry; Compared with the existing electromagnetic shielding film, the whole structure is simple, the thickness of the shielding layer 1um-10um; only and the shielding efficiency can reach -20 to -30dB, at the same time, the adhesive force of the graphene-nano silver composite layer is not less than 4B, which can effectively adhere to the base layer.
