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.
Ionic nanocomposite(NC) hydrogels poly(2-acrylamido-2-methlypropane sulfonic acid-co-acrylic acid-co-N [-3(dimethylamino)propyl] methacrylamide)/Laponite were prepared by in-situ polymerization using ionic monomers 2-acrylamido-2-methlypropane sulfonic acid(AMPS)
acrylic acid(AA) and N [-3(dimethy lamino)propyl] methacrylamide(DMAPMA) in Laponite dispersion. It was found that these hydrogels showed improved mechanical properties with tensile strength of 196 k Pa and elongation at break of 3 805%. Besides
the hydrogel showed p H-sensitive and salt-sensitive behaviors.
