In this present study, Ni layer were plated on polyester nonwoven fabrics (PNFs) surfaces to obtain good electromagnetic interference shielding (EMI-SE). Through scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD), it was found that the PNFs surfaces were successfully modified by the Ni plating. The electrical characteristics of the Ni-PNFs was measured using a 4-point probe electric resistivity tester. The EMI-SE of the Ni-PNFs was tested by a EMI shielding analyzer in the frequency range of 0.5 to 1.5 GHz. As a result, the electroless Ni-PNFs shows good electrical conductivity and shows the effect of good electromagnetic shielding. This means that the Ni particles played a key role in providing the additional conductivity. |
