| Summary: | Highlights Single-atom Fe–N4 sites embedded into graphene were successfully synthesized to exert the dielectric properties of graphene. The absorption mechanisms of metal-nitrogen doping reduced graphene oxide mainly include enhanced dipole polarization, interface polarization, conduction loss and defect-induced polarization. Excellent reflection loss of − 74.05 dB (2.0 mm) and broad effective absorption bandwidth of 7.05 GHz (1.89 mm, with filler loading only 1 wt%) were obtained. |
