Abstract

To achieve the material's synergistic effect for better EMI shielding, this study focuses on evaluating the critical concentration of Magnesium Ferrite (MgFe2O4) nanoparticles with the combination of Graphene and Multi-Walled Carbon Nanotubes (MWCNT) dispersed in a Low-density polyethene (LDPE) polymer medium. Using urea as fuel, a solution combustion synthesis technique was used to create the magnetic filler MgFe2O4. At 900 °C, the calcined nanoparticles exhibit distinct phases. MWCNT and graphene were utilized as conductive fillers. Using a chemical exfoliation procedure, graphene was created. The fillers were analyzed using XRD, FTIR, Raman spectroscopy, SEM, EDS, and VSM. The XRD reveals the MgFe2O4 synthesized from solution combustion synthesis (SCS) is in pure phase without any impurity. The SEM result reveals the morphology of the prepared nanoparticle was Nano sized, well crystalline particles are formed. The composite of LDPE was studied for EMI shielding. The composite sample with a critical concentration of 50 wt. % LDPE, 5wt. % MgFe2O4, 40 wt. % graphene and 5 wt. % MWCNT (50:5:40:5) shows a superior SE value of 33.59 dB at 10.3 GHz.
