摘要：
Ideal electromagnetic absorbing materials with lightweight and high efficiency have broad application outlook in military and civil fields. In this work, a 3D nanostructure material by hybridizing Fe3O4 nanocrystals and reduced graphene oxide (Fe3O4/rGO) were synthesized through an environmental-friendly one-pot solvothermal method. The effect of GO loading on electromagnetic (EM) wave absorption characteristic of Fe3O4/rGO was investigated. The introduction of rGO sheets not only prevented Fe3O4 from agglomerating, also improved the absorption performance of Fe3O4/rGO hybrids. With an appropriate addition, Fe3O4/rGO obtained a minimum reflection loss (RI) of 22.7 dB and the absorption bandwidth was 3.13 GHz (90% absorption).
