Fe3O4-intercalated reduced graphene oxide nanocomposites with enhanced microwave absorption properties
Source abstract
Abstract
Abstract Fe3O4-intercalated reduced graphene oxide (Fe3O4-rGO) nanocomposites were synthesized by an in situ reduction process. The results of XRD and XPS analyses suggested the successful formation of a Fe3O4 crystal phase within the rGO sheets. The SEM and TEM images demonstrated that Fe3O4 was flaky and was inserted stably within the rGO layers to form a typical sandwich-like structure. The hysteresis loops revealed the superparamagnetic behavior of the Fe3O4-rGO nanocomposites at room temperature. The electromagnetic parameters revealed that Fe3O4-rGO nanocomposites exhibited multiple dielectric relaxation and magnetic resonance. The reflection loss revealed that the maximum loss was −49.53 dB at 6.32 GHz for a thickness of 3.4 mm while the highest effective absorption bandwidth was 2.96 GHz.
