Description	Journal: Materials Research Express In this study, we report a facile two step hydrothermal process for the synthesis of MoS2-reduced graphene oxide/Fe3O4 (MoS2-rGO/ Fe3O4) nanocomposite and their application as an excellent electromagnetic interference shielding performer. Various characterization tools like; scanning electron microscope, transmission electron microscope, X-ray diffraction, and Raman spectroscopy were used to characterize the as synthesized nanocomposite. Presence of Fe3O4 nanoparticles with average particle diameter ~ 25-30 nm on the surface of MoS2-rGO composite was confirmed by TEM. Structural characterization was done by XRD and found inconsistent with the known lattice parameter of MoS2 nanosheet, reduced graphene oxide and Fe3O4 nanoparticles. Electromagnetic shielding effectiveness of nanocomposite were evaluated and found as an excellent EMI shielding material in X band range (8.0-12.0 GHz). MoS2-rGO composite shows poor shielding capacity (SET ~ 3.81 dB) in entire range as compared to MoS2-rGO/Fe3O4 nanocomposite (SET ~ 8.27 dB). It is due to interfacial polarization in the presence of EM field. The result indicates that MoS2-rGO/Fe3O4 nanocomposites provide a new stage for the next generation in high-performance EM wave absorption and EMI shielding effectiveness.
