WU Guo-jie, WU Wei-liang, LI Jin-man, et al. The Effects of the Preparation Conditions of Polyvinyl Alcohol-Chitosan Hydrogel on Its Swelling Ration[J]. 2006, 23(3): 16-20.DOI:
Polyvinyl alcohol-chitosan hydrogel is synthesized.The effects of the mass ratio of polyvinyl alcohol and chitosan
the volume of acetum
the concentration of crosslinker on swelling ration are studied and optimized using orthogonal experimental method.The results show that the swelling ration of hydrogel is biggest when gelled at 55℃ with a volume of acetum of 100mL
a polyvinyl alcohol to chitosan ratio of 2
and a concentration of crosslinker of 0.213mol/L.The swelling ration of polyvinyl alcohol-chitosan hydrogel increases when the mass ratio ofpolyvinyl alcohol and chitosan and the concentration of crosslinker reduce and the volume of acetum increases.
