表面活性剂对疏水缔合水凝胶性能的影响
DOI: 10.3724/SP.J.1105.2013.12332, PP. 993-998
Keywords: 水凝胶,疏水缔合,机械强度,溶胀行为,自愈合
Abstract:
通过丙烯酰胺(AM)和丙烯酰胺基十八羧酸钠(NaAAS)共聚合,在没有任何外加化学交联剂的情况下,分别在水溶液和十二烷基硫酸钠(SDS)溶液中通过自由基聚合制备了疏水缔合水凝胶,命名为HA凝胶和SHA凝胶.系统研究HA凝胶和SHA凝胶的机械拉伸性能发现,调节AM和NaAAS的含量,可以使SHA凝胶具有相较不含SDS的HA凝胶更好的力学拉伸性能.HA凝胶在水中不溶解且在纯化和溶胀过程中几乎没有损失,而SHA凝胶体系中的SDS可以扩散出凝胶网络溶解到水中,使得SHA凝胶表现出更加明显的溶胀-去溶胀-平衡溶胀行为;在盐水中由于疏水缔合得到加强,HA凝胶和SHA凝胶都表现出化学凝胶的溶胀特点.在常温下HA凝胶不能实现自愈合,而SHA凝胶具有较好的自愈合能力,并且自愈合效果可以通过SHA凝胶中SDS和聚合物固含量调节.
