▎ 摘　　要

NOVELTY - An iron-based graphene composite material is prepared by preparing ferric oxide powder, multi all carbon nanotubes and graphene oxide powder, putting iron powder into deionized water, adding multi-walled carbon nanotube and graphene oxide powder into de-ionized water to obtain suspension A; carrying out ultrasonic dispersion to suspension A to obtain dispersion liquid A; subjecting dispersion liquid A to microwave heating to obtain dispersion liquid B, and magnetic force stirring to obtain high pressure atomization liquid, and performing high pressure atomization to obtain iron-based graphene composite material powder; and calcining material powder, performing dispersing treatment, performing isostatic cool pressing treatment, obtaining material block, heat pressing, and sintering to obtain desired composite material. USE - Method for preparing iron-based graphene composite material. ADVANTAGE - The material has high heat conduction and improved mechanical property. DESCRIPTION OF DRAWING(S) - The drawing is a schematic diagram illustrating a method for preparing iron-based graphene composite material (Drawing includes non-English language text).
