摘要

为克服磁性金属密度大、磁损耗模式单一等不足,分别以Co盐和均苯三甲酸为原料和有机配体,利用沉淀法制备Co基金属有机框架,通过煅烧处理合成磁性金属Co/C复合微波吸收剂粉末,研究煅烧温度对Co/C微波吸收剂形貌和微波吸收性能的影响。结果表明:煅烧温度对Co/C微波吸收剂的形貌和性能有很大影响,经过500 ℃和600 ℃煅烧分别获得分散均匀的颗粒结构和多孔骨架结构,700 ℃和800 ℃煅烧获得链式棒状结构。800 ℃煅烧的样品表现出最佳电磁波吸收性能,当测试样品厚度为4.5 mm时,其在13.76 GHz处的最大反射损耗和有效吸收带宽分别达到-35 dB和0.56 GHz。微波吸收性能的提高归因于多重损耗机制(涡流和交换共振等),适宜的电磁参数和衰减常数,以及多孔结构与多种组分之间的协同效应。

Abstract

To overcome the drawbacks of high density and single-mode magnetic loss in magnetic metals, Co-based metal organic frameworks were prepared by precipitation method using Co salt and trimesic acid as raw material and organic ligand, respectively. Magnetic metal Co/C composite microwave absorber powders were synthesized through calcination, and the effects of calcination temperature on the morphology and microwave absorption properties of Co/C microwave absorbers were studied. The results show that calcination temperature significantly affect the morphology and properties of Co/C absorbers, uniformly dispersed particle structure and porous framework structures can be obtained after calcination at 500 ℃ and 600 ℃, respectively, while chain-like rod structures can be obtained at 700 ℃ and 800 ℃. The sample calcined at 800 ℃ exhibits the best electromagnetic wave absorption property, with a maximum reflection loss of -35 dB and an effective absorption bandwidth of 0.56 GHz at 13.76 GHz when the tested sample thickness is 4.5 mm. The improvement in microwave absorption property is attributed to multiple loss mechanisms (such as eddy current and exchange resonance), suitable electromagnetic parameters and attenuation constant, and the synergistic effect between the porous structure and various components.
