NOVELTY - Molybdenum disulfide (MoS2)-ferrous oxide-graphene ternary composite absorbing material comprises aminated graphene aerogel, ferric chloride, urea, surfactant, nano MoS2 hollow microspheres, where the mass ratio of aminated graphene aerogel, ferric chloride, urea and surfactant is 6-15:100:200-400:180-300. USE - Used as molybdenum disulfide (MoS2)-ferrous oxide-graphene ternary composite absorbing material. ADVANTAGE - The absorbing material: has large number of amino groups and imino groups having a strong adsorption effect on ferrous ion(iii), and can generate nano-flower-type three-dimensional porous Fe3O4 uniformly grows on the surface of the graphene aerogel and the sheet structure; has a three-dimensional conductive network, interface polarization effect and good magnetic properties, which endows the composite material with good resistive loss and magnetic loss performance, and enhances the composite materials impedance matching performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the ternary composite absorbing material, comprising (1) adding aminated graphene aerogel and ferric chloride to the ethylene glycol solvent, after the ultrasonic dispersion is uniform, heating to 35-55 degrees C, stirring for 4-10 hours, then adding urea and surfactant tetrabutylammonium bromide, and heating 190-220 degrees c, reacting for 1-3 hours, filtering, washing and drying, placing the solid product in an atmosphere furnace and blow nitrogen, the heating rate is 2-5 degrees C/minute, the temperature is increased to 480-520 degrees C, manintaining temperature and calcining for 2-4 hours to obtain nano-flower-type three-dimensional porous ferrous oxide (Fe3O4) modified graphene; and (2) adding three-dimensional porous Fe3O4-modified graphene and nano-MoS2 hollow microspheres to the distilled water solvent, and after the ultrasonic dispersion is uniform, pouring the solution into the micro-reactor and placing in the reactor heating box and heat it to 100-120 degrees C, reacting for 2-5 hours, filtering and drying.
