Abstract:

Auto-catalyzed film on polyester(PET) surface was prepared through chitosan(CS)/polyvinyl alcohol(PVA) complex film with PdCl2, which successfully initiated the nickel electroless plating afterwards. The CS/PVA complex film has interpenetrating networks(IPN) structure with strong hydrogen bonds in it. The chemical structure of complex film was characterized by Fourier transform infrared spectroscopic(FT-IR) analysis and tensile strength test. After electroless plating, the surface morphology, thermal stability, electromagnetic shielding effectiveness(SE) and adhesion strength of the metallized PET fabric were investigated by scanning electron microscopy(SEM), thermogravimetry(TG), SE test and washing fastness test. The results show that the nickel layer can be obtained on treated PET fabrics with good conductivity, fine uniformity and strong adhesion strength.
