摘要

Electroless composite plating of (Ni-P)-SnO_2 nanoparticles on polyethylene terephthalate (PET) fabric was performed in the laboratory. The (Ni-P)-SnO_2 composite-plated fabric was investigated by means of scanning electron microscope, energy dispersive spectroscopy, thermogravimetric analysis, and X-ray diffraction analysis. The electromagnetic shielding performance, surface resistivity, tensile property, and abrasion resistance were also measured. The results show that the onset decomposition temperature of the Ni-P-plated fabric is higher than that of the (Ni-P)-SnO_2 composite plated-fabric, but is lower than that of the original one. The face-centered cube crystal structure of Ni-P deposition is formed due to the incorporation of nano SnO_2 particles. As compared with the Ni-P-plated fabric, the shielding effectiveness (SE) for the (Ni-P)-SnO_2 composite-plated fabric increases when their weight increasing percentages are identical. However, the abrasion resistance decreases because the layer adhesion strength becomes weaker. As the weight increasing percentage of the Ni-P-plated fabric increases, the surface resistivity decreases but the average SE increases, and the tensile strength and Young's modulus increase but the extension decreases. The add-ons of nano SnO_2 particles (below 0.625 g/L) in the plating solution have little effect on the SE.
