Abstract:
In our research,a conductive silver layer has been developed on polyester fiber by electroless plating.The surface morphology,elemental composition and crystal structure of polyester fiber before and after silver plating have been characterized by field emission scanning electron microscopy(FE-SEM),energy-disperse spectroscopy(EDS) and X-ray diffraction (XRD).The effects of the ethylenediamine concentration,AgNO3 concentration,plating time,and solution temperature on weight gain rate and electrical resistivity of electroless silver plated polyester fiber have been explored.The adhesive strength and corrosion resistance of the electroless silver plated layer have been tested.The results indicate that the electrical resistivity of the fiber can be reduced to 2.31 Ω·cm-1 with optimum process conditions.The layer is of high purity silver with face centered cubic structure.The silver layer has good adhesive strength and corrosion resistance.
