Study on of Preparation and Properties Chitosan/Polyvinyl Alcohol Composite Hydrogels

Chitosan/Polyvinyl alcohol(PVA) composite hydrogel was synthesized.The effects of the mass ratio of PVA and chitosan,the concentration of glutaraldehyde on swelling ratio,and mechanical strength were studied.The results showed that when the mass ratio of PVA and chitosan was 2 and the concentration of glutaraldehyde was 0.213 mol/L,the composite hydrogel with the best performance was obtained.
