Tailoring MOF-based materials to tune electromagnetic property for great microwave absorbers and devices

摘要

Metal-organic framework (MOF) materials have highly sought after in electromagnetic materials and functional devices, due to the unique three-dimensional structure and electronic state. Herein, the tailoring strategy of MOF materials, including MOF precursors and carbonized derivatives, is combed for high-efficiency microwave absorbers. The design idea from microstructure to electromagnetic response is constructed. Based on these theories, the current research progress about MOF-based absorbers is presented, and the effect of microstructure tailoring to electromagnetic property and microwave absorption is revealed. In addition, the application of MOF materials in functional device is outlined. Finally, the current challenges for MOF materials and devices are overviewed, and the future development is expected.
