摘要(Abstract)：

本文以锂藻土(Laponite)为无机交联剂,2-丙烯酰胺-2-甲基丙磺酸(AMPS)、丙烯酸(AA)和N-(3-二甲氨基)丙基甲基丙烯酰胺(DMAPMA)为离子型单体,通过原位自由基聚合方法制备离子型聚(AMPS-co-AA-coDMAPMA)/Laponite纳米复合(NC)水凝胶.在证实纳米复合水凝胶组成和网络结构基础上,系统研究其机械性能及在不同p H缓冲液和盐溶液中的溶胀行为.由于Laponite的均匀分散使水凝胶具有良好的机械性能,其断裂拉伸强度达196 k Pa,断裂伸长率达3 805%,且该纳米复合水凝胶表现出一定的p H和盐敏感行为.

关键词(KeyWords)： Laponite;纳米复合水凝胶;离子型单体;机械性能;环境响应性
