Abstract: Polyvinyl alcohol-chitosan hydrogel is synthesized and the effects of the mass ratio of polyvinyl alcohol and chitosan,the wolume of acetum,the concentration of crosslinker on mechanical properties are studied and optimized by using orthogonal experimental method.The results show that the hardness of hydrogel is the biggest when gelled at 50℃ with a volume of acetum of 80mL,a polyvinyl alcohol to chitosan ratio of 4,and a concentration of crosslinker of 0.213mol/L.The breaking intesity of hydrogel is the biggest when gelled at 50℃with a volume of acetum of 100mL,a polyviny1 alcohol to chitosan ratio of 6,and a concentration of crosslinker of 0.213mo/L.
