Abstract

ABSTRACT Electromagnetic wave (EMW) absorbing materials have attracted much attention in recent years due to the dramatical increase of high-frequency electronic components and devices, which generate electromagnetic (EM) pollution and cause serious electromagnetic interference (EMI). Ceramics and associated (nano)composites are widely investigated as EMW absorbing materials because of their excellent mechanical properties, chemical/thermal stabilities, and oxidation/corrosion resistance. In addition to outstanding EMW absorbing performance, lightweight, flexibility and thermal resistance at high temperatures strongly affect their practical applications. Therefore, this review highlights the recent progress of advanced ceramic-based EMW absorbing materials by evaluating their vital EMW absorption parameters. First, the fundamentals of EMW absorption are briefly summarized, followed by the effects of phase/chemical composition, micro/nano structure, and morphology on the EMW absorbing performance and associated mechanisms. Furthermore, modern strategies for the preparation of lightweight, flexible and thermal resistant EMW absorbing materials are comprehensively reviewed. Finally, the perspectives of advanced-ceramics as EMW absorbing materials are discussed as well.

陶瓷基电磁波吸收材料和轻量化、柔性和热阻概念

近年来，由于产生电磁污染和产生严重电磁干扰的高频电子元件和器件的急剧增加，电磁波吸收材料引起了人们的广泛关注。陶瓷及其相关(纳米)复合材料因其优异的机械性能、化学/热稳定性和抗氧化/耐腐蚀性而被广泛研究作为EMW吸收材料。除了出色的EMW吸收性能外，轻质、柔韧性和高温下的耐热性强烈地影响了它们的实际应用。因此，本文综述了先进陶瓷基EMW吸波材料的最新进展，并对其重要的EMW吸波参数进行了评价。首先，简要总结了EMW吸收的基本原理，然后介绍了相/化学组成、微纳结构和形貌对EMW吸收性能的影响及其相关机理。此外，本文还对近年来制备轻量化、柔韧性和抗热性强的EMW吸波材料的研究进展进行了综述。最后，对先进陶瓷作为电磁波吸波材料的发展前景进行了展望。
