Abstract：In order to prepare the ZnO/C composite and investigate its microwave-absorbing properties, the metal-organic framework MOF-5 was taken as the precursor, and the ZnO/C composite was prepared with the solvothermal method. The phase constituent, microstructure, morphology and properties of ZnO/C composite were analyzed with X ray diffractometer ( XRD) , scanning electron microscope ( SEM) , Fourier transform infrared spectrum analyzer ( FTIR) and vector network analyzer ( VNA) . The results show that the ZnO/C composite possesses the complete cube structure which is completely stacked by sheet structure, and the distribution of ZnO and C is uniform. When the coating thickness is 7 mm, the maximum reflection loss at 17. 18 GHz can reach the maximum amplitude. The ZnO/C composite has good microwave-absorbing properties in both far and over-far infrared regions.
