聚合物PAM/PVP与表面活性剂SDS的相互作用

The Interaction Between Polymer PAM/PVP and Surfactant SDS

本文通过对聚合物PAM/PVP与表面活性剂SDS混合体系的相对粘度和表面张力研究,证明聚合物PAM/PVP与表面活性剂SDS之间存在着明显的相互作用。这两种聚合物很容易和表面活性剂相互作用,通过缔合,形成混合胶束状聚集体,导致溶液粘度剧增。随聚合物溶液中SDS的加入,溶液粘度发生起伏变化,出现最大值(最小值)。而二者的相互作用使体系溶液的表面张力在SDS的临界胶束浓度(CMC)前后呈现先减小后增大,最后趋于平衡的情况。且聚表相互作用使溶液界面的界面张力比纯表面活性剂溶液的界面张力有所升高。

This paper has researched relative viscosity and surface tension of the solution mixed with Polymer PAM/PVP and Suffactant SDS, and proved that the the interaction between Polymer PAM/PVP and Suffactant SDS is exist. These two kind of polymer is easy to interact with the surfactant, and form mixed micelle congeries by association, This reflect on the increase of the viscosity. The viscosity will be changed and appeared a max value （minimum value） along with the increase of surfactant. And the interaction causes the instance that the surface tension of the solution minis before the CMC, causes that the surface tension of the mixed solution is then increase, and finally higher than the surfactant goes balance. And the interaction solution.
