▎ 摘　　要

NOVELTY - High-entropy alloy/graphene composite material with wave-absorbing properties i.e. iron-nickel-chromium-aluminum complex of formula (FeNiCrAl0.2)xdoped with Cy(I), is new. The x and y are the mass fractions of the high-entropy alloy FeNiCrAl0.2and graphene C, respectively, where x = 92-98, and x + y = 100. USE - The material is useful in electronic industry for protecting environment, human health, information security and national defense security. ADVANTAGE - The material: enhances magnetic loss capability and wave-absorbing capability; improves high-temperature oxidation resistance and corrosion resistance; improves impedance matching and attenuation characteristics; mainly contributes magnetic loss by high-entropy alloy, and dielectric loss by graphene; enables multiple electromagnetic wave loss mechanisms to work together to realize excellent impedance matching; absorbs electromagnetic waves to the greatest extent; and achieves the effect of improving reflection loss. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the high-entropy alloy/graphene composite material with wave-absorbing properties.
