NOVELTY - Nano-nickel ferrite-supported graphene-based absorbing material comprises phosphorus-doped graphene oxide, nanoporous nickel ferrite (NiFe2O4), paraffin wax, and the mass ratio of the three is 0.2-0.6:0.4-0.8:1. USE - Nano-nickel ferrite-supported graphene-based absorbing material. ADVANTAGE - The nano-nickel ferrite-supported graphene-based absorbing material enhances electrical loss ability of composite materials, and phosphorus doping produces structural defects and enhances the interface polarization effect of the material, has excellent conductivity and nano-NiFe2O4 with excellent magnetic properties form good impedance matching performance, has synergistic effect, and enhances absorbing performance of the composite. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nano-nickel ferrite-supported graphene-based wave absorbing material, which involves: (A) adding graphene and sodium hypophosphite to the distilled water solvent, placing in an ultrasonic disperser, heating to 40-80 degrees C, at 30-50 KHz, ultrasonically dispersing for 2-4 hours, transferring the solution into the reactor; (B) putting heating box of the reaction kettle, heating to 150-180 degrees C, react for 8-15 hours, filtering, washing and drying to prepare phosphorus-doped graphene oxide; (C) adding phosphorus-doped graphene oxide, nanoporous NiFe2O4 and paraffin to the chloroform solvent, stirring and dissolving; and (D) subjecting solution to ultrasonic dispersion treatment, pouring solution into a film forming mold, fully drying and pressing into a 1mm thin film to prepare a nano-nickel ferrite supported graphene-based wave absorbing material.
