Abstract: Electromagnetic shielding Poly(ethylene terephthalate) (PET) fabrics were prepared by electroless sliver plating. The surface morphology, chemical composition and crystal structure of sliver-coated fabric were characterized by means of FE-SEM, EDS and XRD. Systematic investigations, including thickness, weight gain, surface resistance, anti-static property, tensile strength, elongation, fabric stiffness, fabric draping and air permeability were conducted on PET fabrics before and after electroless sliver plating. The results reveal that the metal-layer was high purity sliver, and the crystal structure of sliver deposit was face cubic central structure. The fabric surface resistance decrease greatly when mass gain increase at the beginning. However, the surface resistance reduce slightly when mass gain heavier than 35%. The Ag-plated polyester fabric had higher anti-static property, tensile strength, elongation, stiffness, and draping, but lower air permeability.
