제목 Effect of silver plating on Electromagnetic Interference Shielding Effectiveness Ag-MWCNTs/Epoxy Composites
초록 Multi-walled carbon nanotubes (MWCNTs) were silver (Ag)-plated chemically to enhance the electromagnetic interference shielding effectiveness of Ag-MWCNTs/Epoxy composites. The morphological properties of the Ag-MWCNTs were characterized by scanning electron microscopy (SEM). The micro-structural and surface characteristics of the Ag-MWCNTs were examined by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. The EMI SE of the Ag-MWCNTs/Epoxy composites was tested by EMI shielding analyzer. From these results, the higher Ag content on the MWCNTs of the composites showed a better EMI SE. The EMI-SE of Ag-MWCNTs/Epoxy composites were measured to be 10 dB from 1 GHz band, which was increased compared to that of the as-received MWCNTs (7 dB). This indicates that the presence of Ag on the MWCNTs can lead to a good EMI-SE due to the EMI adsorption behavior of the metal particles.
