POLYACRYLAMIDE HYDROGEL GRAFTED ONTO POLYETHYLENE diameter of 4.5 cm were chemically grafted with a thin layer of polyacrylamide (PAAm) hydrogel via UV LED photopolymerisation system. From the grammages that were tested, 85 gsm PET was the most favourable to be used as a matrix. the surface hydration layer of hydrogel coating
ATRP initiator BiBB was first immobilized onto PET film primed with polydopamine coating. Afterwards, PAM hydrogel with varying hydrogel thickness was grafted from the surface via SI-ARGET-ATRP in the presence of 83 ppm of CuBr 2, . Finally, AgNPs were loaded onto the PET sample grafted with PAM hydrogel to introduce antibacterial activity.
