Preparation of graphene oxide based on microcrystalline graphite: the study of microwave absorption properties

Abstract

The few-layer MGO-1.0 exhibits a RL min reaching −18.39 dB and an EAB is 3.06 GHz (7.97–11.03 GHz) at the frequency of 9.42 GHz. These originate from the synergistic effects of dipole polarization, defect polarization, and conductive loss.
