电子信息技术的迅速发展,致使电磁污染及干扰问题愈加严重,研制具有"宽、薄、轻、强"综合优异性能的吸波材料显得尤为重要.石墨烯材料因其具有轻质、高导电、大比表面积、强介电损耗等优点,但其阻抗匹配性能较差,损耗机制单一.对其进行异质元素掺杂或进行形貌结构设计,可有效改善其阻抗失配问题.本文基于电磁波吸收理论,阐述了不同维度石墨烯基吸波复合材料的研究进展,详细讨论了不同石墨烯基吸波复合材料的性能和吸波机理.还讨论了石墨烯吸波材料领域目前研究工作中存在的一些不足,最后针对石墨烯基吸波材料未来的研究方向和发展前景进行了展望.
Research Progress of Graphene-based Absorbing Composites
With the rapid development of electronic information technology,electromagnetic pollution and interference have become more and more serious.It is particularly important to develop microwave absorption materials with comprehensive excellent performance of"wide,thin,light and strong".Gra-phene materials have the advantages of light weight,high conductivity,large specific surface area and strong dielectric loss,however,the impedance matching performance is poor and the loss mechanism is single.Interestingly,the impedance mismatch can be effectively improved by doping heterogeneous ele-ments or designing morphology and structure.Herein,based on electromagnetic wave absorption theory,this paper describes the research progress of different dimensions of graphene-based absorbing materi-als,and discusses the properties and microwave absorbing mechanism of different graphene-based ab-sorbing materials in detail.The shortcomings of current research work in the field of graphene absorbing materials are also discussed.Finally,the future research direction and development prospect of gra-phene-based absorbing materials are prospected.
