Abstract Ion exchange alloy films based on styrene-polyvinyl chloride (PVC) were modified by plasma technology using betaine benzene sulfonate (SBMA) as grafting monomer. The optimum modification conditions were investigated by means of electrochemical workstation, scanning electron microscopy (SEM) and infrared spectroscopy (FTIR). The results showed that the modification effect was the best when the mass fraction of SBMA was 5%, the plasma irradiation intensity was 0.75 W/cm2 and the irradiation time was 10 min. After modification, the film surface was compact and smooth, and the resistance of the film was reduced to less than 3 Ω.
