Microwave has been widely used in many fields, including communication, medical treatment and military industry; however, the corresponding generated radiations have been novel hazardous sources of pollution threating human's daily life. Therefore, designing high-performance microwave absorption materials (MAMs) has become an indispensable requirement. Recently, metal-organic frameworks (MOFs) have been considered as one of the most ideal precursor candidates of MAMs because of their tunable structure, high porosity and large specific surface area. Usually, MOF-derived MAMs exhibit excellent electrical conductivity, good magnetism and sufficient defects and interfaces, providing obvious merits in both impedance matching and microwave loss. In this review, the recent research progresses on MOF-derived MAMs were profoundly reviewed, including the categories of MOFs and MOF composites precursors, design principles, preparation methods and the relationship between mechanisms of microwave absorption and microstructures of MAMs. Finally, the current challenges and prospects for future opportunities of MOF-derived MAMs are also discussed.
微波已广泛应用于包括通信、医疗和军事工业在内的许多领域；然而，相应产生的辐射已成为威胁人类日常生活的新型污染危险来源。因此，设计高性能微波吸收材料（MAMs）已成为一项不可或缺的要求。最近，金属有机框架（MOFs）因其结构可调、高孔隙率和大比表面积而被认为是MAMs最理想的前驱体候选材料之一。通常，MOF衍生的MAMs表现出优异的导电性、良好的磁性以及足够的缺陷和界面，在阻抗匹配和微波损耗方面都具有明显优势。在这篇综述中，对MOF衍生的MAMs的最新研究进展进行了深入综述，包括MOFs和MOF复合材料前驱体的类别、设计原则、制备方法以及微波吸收机制与MAMs微观结构之间的关系。最后，还讨论了MOF衍生的MAMs当前面临的挑战和未来机遇。
