| Abstract: | The reduced graphene oxide (RGO)/CoFe2O4/SnS2 composites have been successfully synthesized by two-step hydrothermal processes. TEM results show that CoFe2O4 and SnS2 nanoparticles with both diameters about 5–10 nm are well dispersed on the surface of graphene. Compared with RGO/CoFe2O4 composites, the as-prepared RGO/CoFe2O4/SnS2 composites exhibit excellent electromagnetic (EM) wave absorption properties in terms of both the maximum reflection loss and the absorption bandwidth. The maximum reflection loss of RGO/CoFe2O4/SnS2 composites is ?54.4 dB at 16.5 GHz with thickness of only 1.6 mm and the absorption bandwidth with the reflection loss below ?10 dB is up to 12.0 GHz (from 6.0 to 18.0 GHz) with a thickness in the range of 1.5–4.0 mm. And especially, they cover the whole X band (8.0–12.0 GHz), which could be used for military radar and direct broadcast satellite (DBS). |
