主 题:carbon materials porous electromagnetic wave absorption reflection loss impedance matching
摘 要:随着电磁波(EMW)污染的日益严重,开发高性能电磁波吸收材料(EWAMs)已成为研究热点.碳基EWAMs具有优异的物理、化学稳定性和高导电性带来的强介电损耗.特别是三维(3D)多孔碳基EWAMs在EMW吸收研究领域长盛不衰.3D多孔结构大大降低了材料的密度,有利于EMW的多次反射和散射,优化了阻抗匹配,因此有望实现“低密度、薄厚度、宽吸收带宽、强吸收的目标.在此,我们首先阐明了相关的理论基础和评价方法.之后,我们以材料来源为主线索,总结了3D多孔碳基EWAMs的最新研究进展,并突出了其中一些独特而新颖的观点.最后,提出了3D多孔碳基EWAMs的挑战和前景,这将有助于高性能EWAMs的进一步发展.
