▎ 摘　　要

NOVELTY - An electromagnetic shielding material comprises alkenyl graphene-silicon carbide-nickel oxide nanocomposite, methyl (meth)acrylate, acrylic acid, butyl acrylate, styrene, and dicumyl peroxide in a mass ratio of (5-30):100:(10-20):(15-40):(25-45):(1.5-2.5). USE - Electromagnetic shielding material. ADVANTAGE - The electromagnetic shielding material has high thermal conductivity, excellent electrical conductivity, magnetic properties which produces eddy current loss through excellent polarization, electromagnetic shielding property, and attenuation coefficient of the reinforced material to electromagnetic waves adjusts the dielectric constant and permeability of silicon carbide, in which the nickel oxide modified graphene-silicon carbide nanocomposite fibers achieves impedance matching effect.
