摘要
随着电子信息技术飞速发展,电磁波辐射问题日益突出,引起人们的广泛关注.为了解决电磁污染问题,需要开发重量轻、厚度薄、频带宽和吸收强的电磁吸收材料.作为传统吸波材料的Fe3O4具有较高的磁导率、良好的磁损耗和介电损耗.本文从电磁波吸收基本原理出发,综述了Fe3O4单体及Fe3O4基复合吸波材料的最新研究进展,指出了Fe3O4基材料在电磁波吸收方面存在的不足,并展望了其未来可能的发展方向.
Abstract
With the rapid development of electronic information technology,the problem of elec-tromagnetic 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 electro-magnetic absorbing materials that are lightweight,thin,have a wide frequency band,and strong ab-sorbing 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 die-lectric losses.This article reviewed the latest research progress on Fe3O4 monomers and their compos-ite absorbing materials with other materials based on the basic principles of electromagnetic wave ab-sorption.Finally,the shortcomings of Fe3O4-based absorbing materials in electromagnetic wave ab-sorption were pointed out,and their possible future development directions were discussed.
