| 摘 要： | 以聚衣康酸（PIAc）网络为基础，通过分步互穿聚合物网络（IPN）技术引入了聚丙烯酸（PAAc）网络，制得了一种新的由具有同种官能团的2种聚合物互穿而成的全IPN水凝胶。通过研究聚衣康酸水凝胶、聚丙烯酸水凝胶和IPN水凝胶在不同pH条件下的溶胀性能，发现3种水凝胶随着pH增加，溶胀率变大，均表现出pH敏感性。IPN水凝胶的溶胀规律与聚衣康酸、聚丙烯酸水凝胶的溶胀规律相比有明显的差别。

| Abstract: | In this paper,Polyitaconic acid/ Polyacrylic acid interpenetrating polymer network hydrogel was synthesized.From study of swelling ratios of the PIAc,PAAc and IPN hydrogels in different pH conditions,swelling ratio of the hydrogels increases as the pH rise was found,the hydrogels had pH-sensitive character,but the swelling property of IPN hydrogel was different of the swelling properties of the PIAc and PAAc hydrogels. |
