Abstract:The dielectric-dielectric composite (SRGA) for electromagnetic absorber was fabricated via integrating
Ag(I)-Schiff base coordination compounds (SSBCC) with three-dimensional reduced graphene aerogel
(3D-rGA) powders. SRGA showed excellent electromagnetic wave absorption properties in terms of
reflection loss, absorption band width and absorber thickness. Specially, when the mass ratio of SSBC to
3D-rGA powders was 1:3 (SRGA-25), the maximum value of reflection loss at 2mm was up to ?63.82 dB
and the effective frequency bandwidth of 6.28 GHz (10.16e16.44 GHz) at 2.5 mm can be obtained. The
mechanism investigation of electromagnetic wave absorption for SRGA showed that the enhanced
electromagnetic wave absorption was ascribed to enhanced polarization loss derived from good 3D-
conductive-network units of 3D-rGA, abundant interfaces caused by the media heterostructure due to
the introduction of SSBCC and the good impedance matching condition. And 3D-rGA based materials
might be put into
