SYNTHESIS OF REDUCED GRAPHENE OXIDE - Mn0.8Zn0.2Fe2O4 - POROUS POLYANILINE NANOCOMPOSITE MATERIALS FOR EFFECTIVE MICROWAVE ABSORPTION IN X-BAND

Tóm tắt

In this paper, a composite of reduced graphene oxide (RGO), manganese/zinc ferrite (Mn0.8Zn0.2Fe2O4 - MZF) nanoparticles, and porous polyaniline (PANI) was successfully synthesized to improve microwave absorption properties exclusively in X-band. The experimental results demonstrate that the synthesized ternary composite had RGO nanosheets decorated mostly with MZF nanoparticles, and porous PANI was uniformly coated onto the surface of RGO-MZF. The strong reflection loss value of -60.4 dB at 10 GHz and wide effective bandwidth are effectively achieved with the sample which had thicknesses of 2 mm and contained 33 weight % of product. The marked display of the microwave absorption properties of this composite was associated with their notable structure.
