▎ 摘  要

NOVELTY - Electromagnetic shielding composite material comprises composite film formed by coating protective film as base material, where the composite film is composed of insulating layer, graphene layer, soft magnetic metal alloy layer sequentially formed by high temperature pressing after laminating; where the soft magnet metal alloy layers are formed by a coating slurry made of amorphous or nano-crystalline powder. USE - The electromagnetic shielding composite material is useful in the technical field of electromagnetic shielding, preferably in the field of high-frequency magnetic shielding, high-ultraviolet (UV) magnetic shielding and high-altitude magnetic shielding. ADVANTAGE - The electromagnetic shielding composite material has excellent heat-conducting performance, radiating ability, ductility and flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of electromagnetic shielding composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an electromagnetic shielding composite material. 1Protective film 2Insulating layer 3Graphene layer 4Soft magnetic metal alloy layer
