| 摘 要： | 以连续互穿聚合物网络(IPN)方法制备魔芋葡甘聚糖(KGM)/聚二甲基二烯丙基氯化铵(PDADMAC)水凝胶.用扫描电镜(SEM)表征形貌,并探讨其在不同浓度和不同pH值的NaCl溶液中的溶胀行为.实验表明KGM/PDADMAC水凝胶具有密集的表面凸凹的IPN分子结构特征;该IPN水凝胶的溶胀率随着NaCl溶液浓度的增加而下降,随pH值增加而缓慢增加,当pH大于8时,则呈下降趋势.

| Abstract: | Konjac Glucomannan(KGM)/poly(Dimethyldiallyl Ammonium) Chloride(PDADMAC) interpenetrating polymer network(IPN) gel was synthesized using the sequential IPN mehtod.The morphology of the IPN gel was characterized by SEM.The result showed that the gel surface has intense convex-concave,which is the natural structure of IPN gel.The swelling behavior was studied by immersing the gel in aqueous NaCl solutions at various concentration and pHs.The swelling ratio decreased with an increase in NaCl concentration and ... |
