Silver was deposited on the surface of polyaniline coated polyamide fabrics by electroless plating without using conventional palladium chloride solution as activator.Effects of electroless plating conditions such as the concentrations of silver nitrate, reducing agent glucose, complexing agent ammonium hydroxide, sodium hydroxide in the bath, as well as the depositing time and bath temperature on the rate of metal deposition and the square resistance were studied. Optimum electroless plating conditions were: 30℃, 50 min, with silver nitrate 12 g/L, ammonium hydroxide 100 ml/L, glucose 2.8 g/L, sodium hydroxide 8 g/L. Meanwhile, effects of the intermediate polyaniline layer on the metal crystallite size, texture and corrosion resistance of composite conducting fabrics were discussed. The results showed that the intermediate polyaniline layer between polyamide fabric and silver could effectively improve the conductance, corrosion resistance and laundry resistance of composite conducting fabrics.
