Abstract Co/ZnO/Ti3C2Tx composites were successfully prepared by using metal organic framework (MOF) and two-dimensional titanium carbide composites as precursors via a simple self-assembly process and subsequent annealing treatment. The influence of carbonization temperature on microwave absorption properties was studied in detail. Multiple scattering and reflection and polarization behaviors produced by its unique laminated structure endow the material with excellent performance. When the annealing temperature was 750 °C, the best reflection loss value could reach −44.22 dB at 2.4 mm, and the maximum effective absorption bandwidth was 5.28 GHz at the thickness of 2.4 mm. The microwave absorption mechanism is attributed to dielectric loss, magnetic loss, multiple reflections and scattering. Therefore, Co/ZnO/Ti3C2Tx composites can be used as an idea choice for lightweight and efficient microwave absorbers.

金属有机骨架衍生的 Co/ZnO/Ti3C2Tx 复合材料的构建具有优异的微波吸收性能

摘要 以金属有机骨架（MOF）和二维碳化钛复合材料为前驱体，通过简单的自组装工艺和后续的退火处理，成功制备了Co/ZnO/Ti3C2Tx复合材料。详细研究了碳化温度对微波吸收性能的影响。其独特的层状结构所产生的多重散射和反射和偏振行为赋予了该材料优异的性能。当退火温度为750℃时，2.4mm处的最佳反射损耗值可达-44.22dB，厚度2.4mm处的最大有效吸收带宽为5.28GHz。微波吸收机制归因于介电损耗、磁损耗、多次反射和散射。所以，
