This article provides a detailed summary of the latest progress and understanding of perovskite oxide-based electromagnetic wave (EMW) absorbers. It discusses the fabrication methods, EMW absorption properties, and attenuation mechanisms of selected representative advances. The relationship between metal ion doping and perovskite oxide-based composites and their EMW absorption mechanism is also highlighted. The article concludes with an outlook on the challenges and future trends of perovskite oxide-based absorbers.
With the rapid growth of electronic technology, it has been a serious issue how to effectively eliminate the electromagnetic pollution. Perovskite oxides with unique structures and exceptional physicochemical properties as electromagnetic wave (EMW) absorption materials have attracted increasing attention, and has been developing rapidly in recent years. In this article, the latest progress and understanding of perovskite oxide-based EMW absorbers are summarized in detail. The fabrication methods, EMW absorption properties, and attenuation mechanisms of selected representative advances are illustrated and discussed. Moreover, we focus on the relationship between metal ion doping and perovskite oxide-based composites and their EMW absorption mechanism. Finally, the challenges and future trends of perovskite oxide-based absorbers are prospected. Presenting the researchers with a general description of perovskite oxide-based absorbers is one of the principal purposes of this article, which also can provide guidance for novel perovskite-type EMW absorbers.
