摘要
采用表面张力测定和稳态荧光猝灭技术研究了双子表面活性剂胶束在聚合物聚乙烯吡咯烷酮(PVP)上的聚集数,考察了一个不带电的聚合物和新型双子表面活性剂Gemini-0118之间的相互作用。双子表面活性剂和聚合物混合溶液的表面张力-浓度对数曲线表现出典型的转折点,表明溶液形成了表面活性剂-聚合物的聚集体。聚合物浓度对聚集体形成的影响和聚合物浓度下聚集数的大小也进行了考察。结果表明Gemini-0118与聚合物PVP相互作用较为明显。
The change of the aggregation number of Gemini surfactant micelles on the polymerpolyvinylpyrrolidone(PVP)was systematically investigated via surface tension and steady-state fluorescence quenching technology.Moreover,the interaction between an uncharged polymer PVP and the novel Gemini surfactant of Gemini-0118 was also investigated.The surface tension-log concentration curves of the Gemini surfactant and PVP mixed solutions showed typical turning points,indicating that the solutions have formed the surfactant-polymer aggregates.The effect of the polymer PVP concentration on aggregate formation was also revealed in this work.The results showed that Gemini-0118 had obvious interaction with the polymer PVP.
