Perovskite oxides incorporated with reduced graphene oxide (LaFeO3/rGO) for electromagnetic interference (EMI) shielding

Abstract

In the present work, LaFeO3/rGO-based nanocomposites were synthesized using a chemical route. The as-prepared samples were subjected to calcination at 700°C. To classify their structural and morphological properties, the nanocomposites were characterized using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The findings show that the nanocomposites obtained are 20 nm and have undergone diameter changes at 700 ° C after calcination. The XRD analysis reveals that the composites have a strongly crystalline single-phase structure. In addition, Voigt’s theory was used to compute elastic constants such as Young’s modulus (E), Bulk modulus (K), Shear modulus (G), Poisson’s ratio, and linear compressibility. LaFeO3 perovskites computational structural characteristics were also examined. These microwave absorption belongings of LaFeO3/rGO nanocomposites make them appropriate for electromagnetic interference (EMI) shielding usage.
