In the past decades, great progress in electromagnetic microwave absorption (MA) materials in both civil and military fields have been made due to the high demand for the elimination of electromagnetic interference. Recently, hexagonal boron nitride (h-BN) based materials have been regarded as one of the promising MA composite materials because of their remarkable dielectric property, excellent thermal conductivity, low density, and outstanding chemical stability. Developing efficient h-BN–based MA materials has aroused wide interest, aiming to achieve ideal MA materials with thin thickness, low density, high thermal stability, strong absorption capacity, wide absorption bandwidth, and low filling rate. This review presents an overview of the progresses in h-BN based MA materials. It starts with a brief introduction of the MA mechanism, followed by reviewing the fabrication and potential application of different h-BN–based MA materials. Finally, the research perspectives on the h-BN based MA materials are proposed. It is expected that the research interest in h-BN based MA materials from the basic fabrication to engineering application will be instigated in future.

在过去的几十年中，由于对消除电磁干扰的强烈需求，在民用和军用领域中电磁微波吸收（MA）材料已取得了巨大进步。近年来，基于六方氮化硼（h -BN）的材料因其卓越的介电性能，出色的导热性，低密度和出色的化学稳定性而被视为有前途的MA复合材料之一。开发高效的基于h -BN的MA材料引起了广泛的兴趣，旨在获得厚度薄，密度低，热稳定性高，吸收能力强，吸收带宽宽，填充率低的理想MA材料。这篇综述概述了h的进展-基于BN的MA材料。首先简要介绍了MA机制，然后回顾了基于h -BN的不同MA材料的制造和潜在应用。最后，提出了基于h -BN的MA材料的研究前景。预计将来会引起从基础制造到工程应用的基于h- BN的MA材料的研究兴趣。
