【Abstract】 With the rapid development of electronic information technology, the problem of electromagnetic wave radiation has become increasingly prominent and has attracted widespread attention. In order to solve the problem of electromagnetic pollution, people are committed to developing electromagnetic absorbing materials that are lightweight, thin, have a wide frequency band, and strong absorbing ability. Fe₃O₄, a traditional electromagnetic absorbing material, has always been an important member of the absorbing material family due to its high magnetic permeability, good magnetic and dielectric losses. This article reviewed the latest research progress on Fe₃O₄ monomers and their composite absorbing materials with other materials based on the basic principles of electromagnetic wave absorption. Finally, the shortcomings of Fe₃O₄-based absorbing materials in electromagnetic wave absorption were pointed out, and their possible future development directions were discussed.更多还原
