Zeta potential. Zeta potential determined on pristine (PET), PET treated by plasma (PET/plasma), PET treated by plasma and grafted with BPD (PET/plasma/BPD), PET treated by plasma and grafted with BPD and then subsequently with Ag nanoparticles (PET/plasma/BPD/AgNP), and PET treated by plasma and grafted with Ag nanoparticles previously grafted with dithiol (PET/plasma/AgNP*). HS means data obtained by the streaming current method and Helmholtz-Smoluchowski equation; FM means data obtained by the streaming potential method and Fairbrother-Mastins equation.
