▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide/MXene/titanium dioxide/iron carbide multilevel heterostructure porous microsphere absorbing material comprises (a) dispersing graphene oxide and few-layer Ti3C2TxMXene suspension in deionized water, and stirring evenly to obtain aqueous dispersion of two-dimensional materials, (b) adding the above-mentioned dispersion liquid into an atomizer, spraying the dispersion liquid into a container equipped with liquid nitrogen, collecting the frozen droplets for freeze-drying to obtain GO/MXene porous microspheres, (c) mixing the porous microspheres with metallocene, adding carbon fibers, and reacting in a microwave reactor with a fixed power under an argon atmosphere. USE - Preparation method of reduced graphene oxide/MXene/titanium dioxide/iron carbide multilevel heterostructure porous microsphere absorbing material. ADVANTAGE - The multi-level heterostructure porous microspheres has good electromagnetic wave absorption properties, broad application potential in the fields of electromagnetic stealth and security protection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for reduced graphene oxide/MXene/titanium dioxide/iron carbide multilevel heterostructure porous microsphere absorbing material prepared by the above-mentioned method.
