TL;DR: The residual defects and groups in chemically reduced graphene oxide cannot not only improve the impedance match characteristic and prompt energy transition from contiguous states to Fermi level, but also introduce defect polarization relaxation and groups' electronic dipole relaxation, which are all in favor of electromagnetic wave penetration and absorption as mentioned in this paper.
Abstract: The residual defects and groups in chemically reduced graphene oxide cannot only improve the impedance match characteristic and prompt energy transition from contiguous states to Fermi level, but also introduce defect polarization relaxation and groups’ electronic dipole relaxation, which are all in favor of electromagnetic wave penetration and absorption The chemically reduced graphene oxide shows enhanced microwave absorption compared with graphite and carbon nanotubes, and can be expected to display better absorption than high quality graphene, exhibiting a promising prospect as microwave absorbing material

TL;DR: In this article, the composites of iron oxide and Co-B alloy, which were prepared by a modified chemical reduction method, were characterized by scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDXA), XRD, X-Ray photoelectron spectroscopy (XPS), and vibrating sample magnetometry (VSM).
