摘要

研究了十二烷基硫酸钠和油酸钠对聚丙烯酸基分散水凝胶结构流变性能的影响。结果表明，在20 ~ 40℃范围内，添加表面活性剂的水凝胶组合物的粘度高于单个组分的粘度，且随温度的升高而升高。油酸钠组合物是非牛顿液体，具有触变特性。

Structural-rheological properties of systems based on polymeric hydrogels and anionic surfactants

The effect of sodium dodecyl sulfate and sodium oleate on the structural-rheological properties of a dispersed hydrogel based on polyacrylic acid was studied. It was shown that the viscosity of hydrogel compositions with surfactants is higher than the viscosity of the individual components and increases with increasing temperature from 20 to 40 °C. Compositions with sodium oleate are non-Newton liquids and exhibit thixotropic properties.
