▎ 摘  要

CIPs/ZnO/Graphene ternary lamelliform hybrid with good microwave absorbing properties in low frequency band was prepared via facile high-energy ball milling method. The different components of CIPs, ZnO and graphene are combined tightly as well as the NPs of CIPs and ZnO dispersed on graphene present the polycrys-talline characteristics. The addition of ZnO and graphene can improve the low frequency absorption intensity of ball milled CIPs and reduce the corresponding matching absorption thickness. The maximum reflection loss of -45.57 dB at 0.48 GHz with a - 10 dB bandwidth over the frequency range of 030-0.71 GHz can be achieved at the thickness of 4 mm. The excellent absorption performance of this ternary hybrid is owing to the external planar anisotropy, outstanding dielectric properties, hunk eddy current loss, multiple Debye relaxation processes, superior attenuation characteristics and better impedance matching. In addition, the preparation method used here is pretty simple, thus the as-prepared ternary hybrid is probable for using as a candidate in the absorption of low frequency microwave.
