What is Porous Fe/FeO/Fe2O3 nanorod/RGO composites with high-efficiency electromagnetic wave absorption property about?

Electromagnetic wave absorbers composed of reduced graphene oxide (RGO) and magnetic nanoparticles integrates dielectric and magnetic loss features, which is extremely desirable for enhancing electromagnetic wave absorption ability. Here, porous Fe/FeO/Fe2O3 nanorods/RGO composites (FFORGO) are synthesized via anchoring FeO(OH) nanorods on graphene oxide (GO) through dopamine polymerization followed by thermal reduction treatment. The porous Fe/FeO/Fe2O3 nanorods are anchored on RGO, and crosslinked structure formed in FFORGO composites when the GO addition is higher than 5 mg‧ml−1. The abundant active sites (e.g., functional groups, dangling bonds, and lattice defects), the numerous heterointerfaces (among Fe, FeO, Fe2O3 and RGO) and crosslinked structure trigger multiple dipole polarization, interface polarization and enhanced conductive loss. The EM wave absorption property is optimized by tuning the GO addition. FORGO4 with filler loading of 30 wt% achieves the maximal reflection loss of −24.1 dB at a thickness of 1.9 mm and the effective bandwidth below −10 dB of 3.01 GHz with a thickness of 2.2 mm, owing to the proper ratio of Fe/FeO/Fe2O3 nanorods/RGO and synergistic effect
