中文摘要: 高强度疏水缔合水凝胶（HA-gels）是丙烯酰胺（AM）和少量的疏水单体辛基酚聚氧乙烯（4）醚丙烯酸酯（OP-4-AC）在十二烷基硫酸钠（SDS）水溶液中采用胶束共聚的方法制备的。采用胶束共聚理论、橡胶弹性统计理论及Mooney Rivlin理论，并结合单向拉伸实验数据，对HA-gels的交联网络结构的形成机理进行了探讨。结果表明：HA-gels的交联网络结构的形成机理可以用初始反应液中SDS的胶束浓度与凝胶内有效网链密度的比值进行表征。
Abstract:Hydrophobic association hydrogels (HA-gels) with high mechanical strength were successfully prepared through micellar copolymerization of acrylamide (AM) and small amount of octylphenol polyoxyethylene acrylate (OP-4-AC) in an aqueous solution containing sodium dodecyl sulfate (SDS). On the basis of the micellar copolymerization theory, the statistical molecular theory of rubber elastic, the Mooney Rivlin theory, and using uniaxial stretching data, formation mechanism of cross linked network structure of HA-gels were investigated. Results show that the formation mechanism mentioned above could be characterized with ratio of SDS micellar concentrations in the initial solution to the effective network chain density of HA-gels.
