▎ 摘　　要

NOVELTY - Graphene nonwoven fabric electromagnetic shielding composite material comprises a nonwoven fabric body and a graphene conductive layer coated on the fiber surface and fiber gap of the nonwoven fabric body of the fiber net. The mass ratio of the nonwoven fabric body and the graphene conductive layer of the optical fiber net is 5-20:1. USE - Used as graphene-non-woven fabric electromagnetic shielding composite material. ADVANTAGE - The graphene nonwoven fabric electromagnetic shielding composite material is light, soft, and has excellent conductivity and electromagnetic shielding performance. The graphene nonwoven fabric electromagnetic shielding composite material is prepared without metal blending or metal plating layer, which greatly shortens the process flow and cost, simple and easy, high efficiency, high operability, and is good for industrial mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the graphene non-woven fabric electromagnetic shielding composite material, comprising thermally strengthening the surface of the non-woven fabric web to obtain a reinforced non-woven fabric net, coating the reinforced non-woven fabric net with graphene conductive ink and drying to obtain a graphene-coated non-woven fabric net, and hot-rolling the graphene-coated non-woven fabric net. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method for preparing graphene non-woven fabric electromagnetic shielding composite material (Drawing includes non-English language text).
