Multi-walled carbon nanotubes(MWCNTs) were treated using concentrated nitric acid, and the microwave absorp-tion and infrared radiation performance of Multi-walled carbon nanotubes/ Zinc oxide ( MWCNTs/ ZnO) composite materials were studied, which were prepared by chemical precipitation methods. XRD, SEM, FT-IR and TG were used to characterize the struc-ture, morphology and thermal stability of MWCNTs/ ZnO composites. The microwave absorption properties and infrared emissivity of MWCNTs/ ZnO composites were measured by vector network analyzer and IR-2 Infrared emissometer, respectively. The results showed that the largest reflection loss of the MWCNTs/ ZnO composites was - 4. 5 dB in the frequency range of 2-18 GHz and the lowest infrared emissivity was 0. 81 in 8-14 μm wave band.
