Recent Research Progress of Ferrite Multielement Microwave Absorbing Composites

Abstract

With the extensive application of electrical and wireless equipment, several electromagnetic pollution‐related issues have emerged. Therefore, the manufacturing of absorbing materials has become important to electromagnetic pollution. Ferrite is a common absorbing material; its single absorbing mechanism and narrow absorbing frequency band resist the wider usage as an ideal absorbing material. Adding different materials to ferrite has become a popular way to enhance its microwave absorption properties. Herein, the recent research on ferrite multicomponent microwave absorbing composites is summarized. For ferrite binary composite absorbing materials, the research progress of ferrite and graphene, carbon nanotubes, carbon fiber and other carbon materials, ferrite and polypyrrole, polyaniline and other polymer materials, and ferrite and MXene composites is introduced. In addition, the advancement of ferrite ternary absorbent materials research is also discussed. The growing development trend of ferrite composite absorbing materials is finally summed up, and the prospects of fabricating the “thin, light, wide, and strong” ferrite absorbing materials are put forward.
