Attaining nanocomposites having high mechanical and electrical properties simultaneously via carbon based nanomaterials remains exciting as carbon nanomaterial have a pattern of formation of random dispersive networks in polymeric nanocomposites. Here, polycarbonate/ethylene methyl acrylate blend (PC/EMA) nanocomposites were fabricated using graphene to explore their effect on electrical, mechanical, and electromagnetic interference (EMI) shielding properties. The mechanical properties of the nanocomposites are improved by enhancing the graphene content. EMI shielding properties of graphene based composites were calculated in X band. The fabricated PC/EMA-graphene nanocomposites showed an EMI shielding of -51 dB for 15 phr graphene loading. Thus, the excellent EMI shielding performance and sensitive response combination make the nanocomposites promising material for many potential applications in next-generation electronics.
