采用自由基水溶液聚合法,分别合成了聚(丙烯酰胺-co-甲基丙烯酸钠)(P(AAM-co-NMA))水凝胶和不同MWNTs-COOH含量的新型聚(丙烯酰胺-co-甲基丙烯酸钠)/羧基碳纳米管(P(AAM-co-NMA)/MWNTs-COOH)复合水凝胶.结果发现,P(AAM-co-NMA)和羧基碳纳米管(MWNTs-COOH)之间表现出良好的兼容性.当MWNTs-COOH的含量为1.5％时,P(AAM-co-NMA)/MWNTs-COOH复合水凝胶表现出较高的膨胀性能和最佳的力学性能.同时发现这种复合水凝胶具有优良的pH值敏感性.因此MWNTs-COOH含量为1.5％的复合水凝胶有望被应用在药物控释和组织工程方面.
