This study aimed to investigate the optimal electroless silver plating conditions on poly (ethylene terephthalate) (PET) to develop electromagnetic shielding fabrics by comparison with two different activation agents (silver nitrate mixture and palladium chloride mixture).

The electromagnetic wave shielding effectiveness and electrical conductivity of plated fabrics were maintained even after repeated laundering cycles. Electron probe microanalysis was concluded that the silver was attached on plated PET surfaces, and about 17.8% of silver was observed by inductive coupled plasma spectrometer.
