Abstract

Increasing demands of microwave absorbents require new approaches to enhance the absorbing performance. Metal−organic frameworks (MOFs) could be developed as effective absorbers owing to their outstanding features including intrinsic porosity and high specific area. Herein, novel nanostructured Co-MOF-74 composites have been successfully fabricated via a simple solvothermal method. Excellent absorption performance was achieved for the composite with a minimum reflection loss (RL) of −25.5 dB at 2.5 mm and a broad absorption bandwidth (RL < −10 dB) of 6.7 GHz. Such absorber could be developed as lightweight and high-efficiency absorbing materials, and this work provides inspiration for the design of advanced absorbers with strong dissipation capacity and broad effective bandwidth.
人们对微波吸收材料的需求不断增加,需要新的方法来提高吸收性能。金属有机骨架(MOFs)具有固有孔隙率高、比表面积大等特点,是一种有效的吸收材料。本文通过简单的溶剂热法成功制备了新型纳米结构的Co-MOF-74复合材料。该复合材料具有优异的吸收性能,在2.5 mm处的最小反射损耗(RL)为- 25.5 dB,吸收带宽(RL < - 10 dB)为6.7 GHz。该吸波材料可发展为轻量化、高效的吸波材料,为设计耗散能力强、有效带宽宽的先进吸波材料提供了启示。
