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Fe_(3)O_(4)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Fe_(3)O_(4)单体及Fe_(3)O_(4)基复合吸波材料的最新研究进展,指出了Fe_(3)O_(4)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.
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.Fe_(3)O_(4),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 Fe_(3)O_(4) monomers and their composite absorbing materials with other materials based on the basic principles of electromagnetic wave absorption.Finally,the shortcomings of Fe_(3)O_(4)-based absorbing materials in electromagnetic wave absorption were pointed out,and their possible future development directions were discussed.
