| description | Alarming shoots up in the field of technology and communication raise the interest of researchers towards materials to reduce electromagnetic (EM) pollution. In this view, mesoporous La0.5Sr0.5Fe0.5Mn0.5O3 (LSFMO) was synthesized by a dual impregnation process using SBA-15 as a template. The LSFMO was mixed with graphene oxide, which is synthesized using a modified Hummer's method in different weight ratios (1:0, 1:2, 1:1, 2:1, 3:1) to prepare composites by in-situ reduction of Graphene Oxide (GO). The structural properties were investigated using XRD, FE-SEM, FT-IR and nitrogen adsorption/ desorption isotherm. The in-situ synthesis illustrates the growth of mesoporous LSFMO on the layers of reduced graphene oxide having an effective surface area of 31.6 m2g−1. The composite La0.5Sr0.5Fe0.5Mn0.5O3-RGO (LSFMG31) showed good electrical conductivity of 53.66 S/m with high shielding effectiveness (SE) of 57.63 dB (∼99.999% of attenuation of electromagnetic waves) in Ku- band ranges from 12.4-18 GHz at 2.85 mm thickness. The shielding effectiveness is mainly dominated by absorption, which may be further utilized for commercial applications. |
