Abstract
An environmentally friendly modified method by UV radiation was used to rapidly deposit polydopamine on the surface of PET fabric, utilising adsorption of polydopamine to metal ions to achieve silver activation on the surface of modified PET fabric, further electroless nickel-plating with non-palladium. By UV radiation, the reaction time of dopamine in alkaline aqueous was shortened to less than 30 minutes. Meanwhile the results of scanning electron microscopy, X-ray diffraction analysis, X-ray photoelectron spectroscopy successfully confirmed that dopamine molecules can form polydopamine functional thin film rapidly on the PET fabric, which was able to be used to electroless nickel-plating for the next step; the nickel-plating coating of modified polyester was uniform and compact; the plating coating was Ni–P alloy with low resistivity.
