摘要:

隨著微波技術的迅速發展，吸波材料在電子設備可靠性、醫療保健與國防安全等方面發揮著越來越重要的作用。具有厚度薄、質量輕、吸波頻帶寬且吸收能力強等優異性能的吸波材料引起了研究者們的極大興趣。近年來，碳基材料由于密度低、比表面積大、介電損耗強和導電性高等特點，逐漸發展成為一類高性能吸波材料。首先，簡述了吸波材料的吸波機理，并從還原氧化石墨烯（RGO）基、碳納米管基與多孔碳基吸波材料3方面詳細綜述了近年來碳基吸波材料的研究進展。其次，圍繞電磁參數的調控、阻抗匹配特性的提高與多種損耗機制的創建等影響吸波性能的關鍵因素，討論分析了目前提高碳基材料吸波性能的方法。此外，還指出了目前碳基吸波材料存在的缺點、面臨的挑戰和發展前景，為吸波領域開展相關研究工作提供了借鑒。

Abstract:

With the rapid development of microwave technology, microwave absorption materials (MAMs) are playing a more important role in electronic reliability, healthcare, national defense security. High performance MAMs with thin thickness, low density, wide microwave absorption bandwidth and strong absorption have attracted researchers-great interests. Recently, owing to their low density, high specific surface area, strong dielectric loss and high electronic conductivity, carbon-based materials have been gradually developed into a kind of high-performance MAMs. Firstly, the mechanism of microwave absorption was briefly described. And the research progress on carbon-based MAMs, including reduced graphene oxide(RGO) based composites, carbon nanotubes based composites and porous carbon based composites, was reviewed. Furthermore, the methods of improving the microwave absorbing performance for carbon-based materials were discussed and analyzed. It is mainly around the critical factors which have influence on microwave absorbing performance by regulating electromagnetic parameters, improving impedance matching and establishing various loss mechanisms. Moreover, the shortcomings, challenges, and prospects of carbon-based MAMs were also put forward, which laid the foundation for developing researches in related fields.
