摘要: 采用热处理的方法制备出二维层状Ti3C2Tx/Ni/TiO2复合粉体,并利用TG-DSC、SEM、XRD和XPS对样品进行表征分析,通过矢量网络分析仪测试样品的电磁参数并模拟计算不同涂层厚度下样品的反射损耗值(RL)。结果表明:随着热处理温度的升高,样品中TiO2质量含量增加;当热处理温度为300 ℃时,在频率f=17.5 GHz下样品的RL为-35.2 dB,其有效吸波带宽超过1.7 GHz,对应的涂层厚度为4 mm。其优异的吸波性能一方面来自良好的阻抗匹配,另外一方面来自样品的介电损耗、磁损耗的协同效应。此外,样品的电磁波吸收能力可以通过其组分和微观结构进行调控。

Abstract: A two-dimensional layered Ti3C2Tx/Ni/TiO2 composite powder was prepared by the heat treatment method.The samples were characterized and analyzed by TG-DSC,SEM,XRD and XPS.The electromagnetic parameters of the composite were measured by a vector network analyzer and its reflection loss(RL) under different coating thicknesses were calculated.The results show that the TiO2 mass content in the product gradually increases as the heat treatment temperature increases.When the heat treatment temperature reaches 300 ℃,RL of the sample is -35.2 dB at f=17.5 GHz,and its effective absorption amplitude exceeds 1.7 GHz,corresponding to the thickness is 4 mm,and its excellent electromagnetic wave absorption performance due to the good impedance matching and the synergistic effect of the dielectric loss and magnetic loss of the sample.In addition,the sample electromagnetic wave absorption ability is modeled by their composition and microstructure.

Key words: MXene, two-dimensional layered Ti3C2Tx, Ti3C2Tx/Ni/TiO2 composite powder, heat treatment, electromagnetic wave absorption
