Abstract:
With polyvinyl alcohol (PVA) and acrylamide (AM) as raw material, PVA/PAM hybrid doublenetwork hydrogel was synthesized by onepot twostep polymerization method combined UV irradiation and freezingthawing technology. We tested and analyzed the mechanical property, swelling property, water loss property and selfhealing property of hydrogels. The results show that PVA/PAM hybrid doublenetwork hydrogel has high mechanical strength, its tensile strength is 428 kPa, the water loss rate is slower than the single network hydrogel. The hybrid doublenetwork hydrogel possesses selfhealing property.
Key words: polyvinyl alcohol (PVA), acrylamide (AM), irradiation, freezingthawing, hydrogel, mechanical property, selfhealing
