摘　　要：以壳聚糖和聚醚为原料,戊二醛为交联剂,在醋酸溶液中制备了壳聚糖/聚醚水凝胶,反应温度45℃,聚醚和壳聚糖的质量比为0.4,戊二醛浓度为0.053 mol/L,壳聚糖黏均相对分子质量为24.86×104时,其凝胶饱和溶胀度为876.25%;反应温度45℃,聚醚和壳聚糖的质量比为0.6,戊二醛浓度为0.267 mol/L,壳聚糖黏均相对分子质量为24.86×104时,其凝胶硬度为151.896 kPa。Chitosan/polyether semi-interpenetrating polymer network （semi-IPN） hydrogel was prepared in acetic acid solution with chitosan and polyether using glutaraldehyde as crosslinker. When the reaction temperature was 45℃, mass ratio of polyether to chitosan was 0. 4, concentration of the crosslinker was 0. 053mol/L,and viscosity average relative molecular weight of chitosan was 24. 86 ×10^4,the saturated swelling ratio of the hydrogel was 876. 25% ;when the reaction temperature was 45℃ ,mass ratio of polyether to chitosan was 0. 6, concentration of the crosslinker was 0. 267 mol/L, and viscosity average relative molecular weight of chitosan was 24. 86×10^4, the hardness of the hydrogel was 151. 896 kPa.
