Appraising the dielectric properties and the effectiveness of electromagnetic shielding of graphene reinforced silicone rubber nanocomposite

Abstract The aim of this research is to measure the dielectric properties and electromagnetic interference (EMI) shielding effectiveness (SE) silicone rubber reinforced with graphene nanoplates. In a two-roll mill, different amounts are mixed together. This followed by compression moulding at 170°C post-curing for 4 h 200°C. Between 1 MHz GHz, waveguide transmission line method vector network analyser used EMI SE parameters. As amount increased from 0 7 wt%, AC conductivity goes up, reaching 1.19 × 10 −3 S/cm wt%. same composition gives highest 43.22 dB GHz. high-frequency structural simulation compositions shows how works, results agree what has been seen in experiments.
