One-Pot Hydrothermal Preparation of Fe(3)O(4) Decorated Graphene for Microwave Absorption

Fe(3)O(4) decorated graphene was synthesized for electromagnetic wave absorption via a facile one-pot hydrothermal approach. The structure and morphology of the as-prepared nanomaterials were systematically investigated. The graphene oxide (GO) was reduced and Fe(3)O(4) nanoparticles were evenly dec...

description Fe(3)O(4) decorated graphene was synthesized for electromagnetic wave absorption via a facile one-pot hydrothermal approach. The structure and morphology of the as-prepared nanomaterials were systematically investigated. The graphene oxide (GO) was reduced and Fe(3)O(4) nanoparticles were evenly decorated on the surface of reduced graphene oxide (rGO) nanosheets. The average particle size of Fe(3)O(4) nanoparticles is about 15.3 nm. The as-prepared rGO-Fe(3)O(4) nanocomposites exhibited a good microwave absorption performance because of the combination of graphene and magnetic Fe(3)O(4). When the thicknesses are 1.6 mm and 6.5 mm, the reflection loss (RL) values are up to −34.4 dB and −37.5 dB, respectively. The effective bandwidths are 3.8 and 1.9 GHz.
