▎ 摘　　要

NOVELTY - Electromagnetic shielding composite material i.e. a polyester-based nano-copper-reduced graphene oxide composite material obtained by taking polyester fabric as a base material, loading nano-copper and graphene oxide, and reducing graphene oxide, is claimed. The preparation of nano-copper emulsion comprises adding nano-copper particles into distilled water, adding butyl acrylate, methyl methacrylate, n-hexadecane and sodium lignosulfonate in turn, magnetically stirring, stirring uniformly, ultrasonically dispersing in an ice-water bath, heating to 70-80°C, adding potassium persulfate and continue to react for 2-3 hours. USE - Used as electromagnetic shielding composite material. ADVANTAGE - The composite material is belonging to the technical field of materials that reflect radiation and shield electric fields and magnetic fields, and has good electromagnetic shielding performance, high hydrophilic performance, light weight, softness, and good hand feeling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the electromagnetic shielding composite material.
