- W3136142318 abstract "Core-shell Fe3O4@poly(3,4-ethylenedioxythiophene) (PEDOT) microspheres are compounded with reduced graphene oxide (rGO) to prepare Fe3O4@PEDOT/rGO composite as an efficient electromagnetic (EM) wave absorber. The microstructure, element composition, morphology and saturation magnetization are characterized, and EM wave absorption properties are analyzed in the frequency range of 2.0–18.0 GHz. The results show that PEDOT is polymerized on the surface of Fe3O4 microspheres, and prepared core-shell microspheres are supported on rGO nanosheets. The reflection loss (RL) of Fe3O4@PEDOT/rGO composite is −48.8 dB at 9.12 GHz, and effective absorption bandwidth (EAB) (RL < −10 dB) is 4.32 GHz, when the matching thickness is 2.9 mm. Additionally, when the matching thickness is 2.1 mm, the EAB covers 7.20 GHz. The excellent absorption performance benefits from good impedance matching, attenuation characteristic, synergistic effect of dielectric and magnetic loss, and the absorption mechanism is explained in detail in the article. Furthermore, radar cross section (RCS) analysis is adopted to simulate and calculate EM scattering performance of Al metal plate with absorption coating. The results demonstrate that Fe3O4@PEDOT/rGO composite exhibits enhanced absorption performance and can be used as an excellent EM wave absorber." @default.
