Reduced Graphene Oxide/Fe₃O₄/Polyaniline Ternary Composites as a Superior Microwave Absorber in the Shielding of Electromagnetic Pollution.

ABSTRACT: The present work is focused on fabrication of reduced graphene oxide/iron(II/III) oxide/polyaniline (RGO/Fe₃O₄/PANI) ternary composite by a hydrothermal method, its characterization, and application in the development of a high microwave absorbing shielding material. The RGO/Fe₃O₄/PANI composite showed dramatic enhancement of dielectric loss and magnetic loss compared to Fe₃O₄/PANI and RGO/Fe₃O₄ binary composites. This is ascribed to the embedment of more heterostructure phases. As a result, RGO/Fe₃O₄/PANI showed remarkably high SE_T (∼28 dB) through the absorption dominant mechanism. Our findings also showed maximum R _L of Fe₃O₄/PA
