摘要

Nowadays,metal oxide-based electromagnetic wave absorbing materials have aroused widely attentions in the application of telecommunication and electronics due to their selectable mechanical and outstanding dielectric properties.Herein,the binary ZnO/NiCo2O4 nanoparticles were successfully synthesized via hydrothermal reaction and the electromagnetic wave absorption properties of the composites were investigated in detail.As a result,benefiting from the dielectric loss,the as-obtained ZnO/NiCo2O4-7 samples possessed a minimum reflection loss value of-33.49 dB at 18.0 GHz with the thickness of 4.99 mm.This work indicates that ZnO/NiCo2O4 composites have the promising candidate applications in electromagnetic wave absorption materials in the future.
