Abstract
To construct effective electromagnetic parameters of reduced graphene oxide (RGO)-based composites for lightweight and high efficiency microwave absorption, Ni/RGO composites were prepared via a facile in-situ hydrothermal process. Due to the strong high-frequency polarization effect related to the large surface contact area of the obtained Ni/RGO hybrids, the composites presented strong electromagnetic wave attenuation ability even when the filler content is only 1.6 wt. %. This work might deepen the understanding of the effective dielectric loss mechanism and impedance matching and provide an effective strategy for the practical application of RGO as a lightweight and high-performance microwave absorption material.
