A carbon magnetic synergistic composite material based on reed carbon-graphene oxide heterostructure, its preparation method and application

Abstract

This invention belongs to the field of electromagnetic wave absorbing materials technology, specifically relating to a carbon-magnetic synergistic composite material based on a reed carbon-graphene oxide heterostructure interface, its preparation method, and its applications. The composite material provided by this invention includes a resin matrix and self-assembled carbon magnetic materials dispersed in the resin matrix; the self-assembled carbon magnetic materials include electrostatically self-assembled heterostructured carbon materials and modified carbonyl iron powder; the heterostructured carbon materials include porous reed carbon and graphene oxide supported on the porous reed carbon; the modified carbonyl iron powder includes carbonyl iron powder and an organic molecular modification layer coating the surface of the carbonyl iron powder. The carbon-magnetic synergistic composite material provided by this invention significantly enhances interfacial polarization loss, improves impedance matching, and achieves electromagnetic synergistic dissipation, thus possessing excellent electromagnetic wave absorption capabilities and showing broad application prospects as a wave absorbing material.
