Factors affecting electroless plating copper on polyester/polyaniline composite fabrics

Copper was evenly deposited on the surface of polyester/polyaniline composit fabric by electroless plating assisted with ultrasonic technology.The effects of depositing conditions of polyaniline,sensitization and activation conditions of the electroeless plating and assisting conditions of ultrasonic technology on surface resistivity,weighting percentage,and adhesive force of the composite fabrics were investigated.The corrosion resistance of polyester/polyaniline,polyester/copper and polyester/polyaniline/copper composite fabrics was compared by dipping and anodic polarization.The morphology of the samples was characterized by scanning electron microscope(SEM).The results indicated that using polyaniline as intermediate conductive layer reduces the surface resistance of the metallized fabric,enhances the adhesive force between the metal and fabric,and increases the corrosion resistance of the conductive composite fabric.Introduction of ultrasonic technology promotes even depositing of copper on the surface of composite fabrics.
