摘要
通过对聚合物聚丙烯酰胺/聚乙烯吡咯烷酮(PAM/PVP)与表面活性剂十二烷基硫酸钠(SDS)混合体系的相对黏度和表面张力研究,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,通过缔合,形成混合胶束状聚集体,导致溶液黏度剧增。随聚合物溶液中SDS的加入,溶液黏度发生起伏变化,出现最大值(最小值)。而2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 studied the relative viscosity and surface tension of the solution mixed with polymer PAM/PVP and surfactant SDS,confirming the existence of the interaction between them.These two kinds of polymer were easy to interact with the surfactant,forming the mixed micelle congeries by association and resulting in the increase of the viscosity.The viscosity would be changed to a maximum value(minimum value)along with the increase of surfactant.And the interaction caused the instance that the surface tension of the solution declined before the CMC,then increased and finally went balance.As the result,the surface tension of the mixed solution was higher than the surfactant solution.
