Review of Graphene/Ferrite Nanocomposites for Microwave Absorption

At present, electromagnetic wave pollution is becoming increasingly severe, which urgently needs to be solved; thus, wave-absorbing materialshave been developed and applied rapidly. Graphene has the advantages of wideband absorption, high electrical conductivity, light weight, etc. Ferrite has the advantages of high permeability, low magnetic loss, wide operating frequency, etc. To complement each other's advantage, the graphene/ferrite composites have become important materials in the field of wave absorption due to their thin and light properties, high absorption rate, and multimechanism loss. In this review, first, the mechanism and classification of absorbent materials are described systematically. Second, the purpose, method, and properties of graphene composite with different types of ferrites are introduced. Third, the future prospect of graphene/ferrite composite absorbing materials is presented. This work will help researchers gain a deeper understanding of the broad development prospects and application fields of graphene/ferrite composites.
