This work reported preparation of hybrid composites using a simple method, and the fabricated composites containing hybrid carbon nanomaterials performed excellent EMI shielding properties. Silver particles-based graphene hybrid have been synthesized and high performance shields for EMI in the microwave region have been developed. Morphological characterization of Ag-carbon hybrid composites by scanning electron microscopy and X-ray diffraction revealed (diameter: 3–8 um) decorated carbon materials. The Ag-carbon hybrid composites showed excellent shielding response, which is majorly governed by absorption losses. The results show that the total EMI shielding effectiveness (SE) value is 61 dB for Ag-carbon hybrid composites at 20 um thickness. The presence of carbon materials on Ag particles enhances space charge polarization, multiple scattering and effective anisotropy energies of the Ag-carbon hybrid composites, resulting in high EMI effectiveness. |
