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
