中文摘要：
以壳聚糖、丙烯酸、甲基丙烯酸羟乙酯为原料,硝酸铈铵、过氧化二苯甲酰为引发剂,戊二醛为交联剂,制备了壳聚糖-丙烯酸-甲基丙烯酸羟乙酯复合水凝胶,探讨了凝胶溶胀过程和理论,研究了凝胶合成条件及溶剂性质对凝胶平衡溶胀度的影响.结果表明：随着丙烯酸浓度、甲基丙烯酸羟乙酯添加量的增加,凝胶平衡溶胀度先增大再减小,凝胶溶胀度随着戊二醛浓度增加而减小.壳聚糖-丙烯酸-甲基丙烯酸羟乙酯复合水凝胶是pH/离子/温度敏感型凝胶.
英文摘要：
A Cs-AA-HEMA complex hydrogel was synthesized in acrylic acid solution from chitosan-acrylic acid-hydroxyethyl methacrylate as raw materials, cerium ammonium nitrate, benzoyl peroxide as initiator and glutaraldehyde as crosslinker. The process and theory of hydrogel swelling were studied. The effects of various factors such as preparation conditions and solvent properties on the degree of equilibrium swelling were investigated. The results showed that the degree of equilibrium swelling ratio of complex hydrogel increased with increasing the concentration of acrylic acid and hydroxyethyl methacrylate first and then decreased afterwards. However, the degree of equilibrium swelling decreased with increasing concentration of glutaraldehyde. The complex hydrogel was pH/ion/temperature-sensitive.
