摘　　要：应用电导率仪测定了聚丙烯酰胺与表面活性剂溶液的电导率,考查了聚合物与表面活性剂的相互作用。应用界面张力仪、表面粘弹性仪和Zeta电位仪测定了油水界面性质,研究了界面性质对乳状液稳定性的影响。结果表明,聚合物与表面活性剂复合能够形成稳定的聚集体,较小的界面张力、较大的界面剪切粘度值以及较高的Zeta电位有利于乳状液的稳定存在。The conductivity of Polyacrylamide and surfactant solution is measure with conductivity tool, and the interaction between polymer and surfactant is studied. The OWC properties are measured with interfacial tensiometer, surface viscoelasticity tool and Zeta potential tool for the research on the influence of interfacial properties on stability of emulsion. The results indicate that PAM and surfactant complex form stable aggregate. The lower interfacial tension, higher interfacial shear viscosity and the higher Zeta potential are favourable for the stability of emulsion.
