N2 - Effective structural design and component optimization is critical for enhancing the performance of electromagnetic wave (EMW) absorbing materials. In this study, CoFe Prussian blue analog/graphene oxide composite (CoFe-PBA/GO) was designed by electrostatic adsorption, in situ growth and co-precipitation deposition and carbon layer-coated CoFe/reduced graphene oxide composite (CoFe@C/RGO) was synthesized via pyrolysis. The carbon layer-coated CoFe (CoFe@C) with core-shell structure is successfully integrated onto the reduced graphene oxide (RGO) surface, effectively preventing the aggregation of RGO nanosheets. The incorporation of RGO facilitates the formation of a continuous conductive network and improves conduction loss. The optimized CoFe@C/RGO-15 has a minimum reflection loss (RLmin) of − 47.88 dB at 9.42 GHz with a thickness of 2.1 mm and effective absorption bandwidth (EAB) is 3.77 GHz (11.98–15.75 GHz) at 1.6 mm. This study provides a novel approach for fabricating of an EMW-absorbing material with dielectric loss and magnetic loss, offering significant insights into low-frequency magnetic attenuation mechanisms.
