摘要

摘要本研究采用表面张力法研究了酯化酰胺gemini表面活性剂c12 -(BAE)-C 12 (BAE代表双(乙氧基)乙烷连接基)与非离子聚合物聚乙烯吡咯烷酮(PVP)的相互作用。结果发现它们之间没有明显的相互作用。通过表面张力、微极性和浊度测量研究了c12 -(BAE)- c12与聚丙烯酸钠(NaPAA)的相互作用。结果表明，两者之间存在较强的相互作用。聚集体是由c12 -(BAE)- c12和NaPAA分子之间的静电吸引形成的。这一过程导致表面张力和微极性曲线上出现临界聚集浓度(cac)和临界胶束浓度(CMC)两个拐点。此外，无机盐NaBr具有促进或抑制c12 -(BAE)-C 12与NaPAA相互作用的两种相反作用。这与NaBr本身的浓度有关。

The interaction of ester functionalized amide gemini surfactants with polymers

Abstract In this study the interaction between the esterified amide gemini surfactant C 12 -(BAE)-C 12 , where BAE stands for the bis(acetoxy)ethane linking group, and the non-ionic polymer polyvinylpyrrolidone (PVP) was investigated by the surface tension method. It was found that there was no apparent interaction between them. The interaction between C 12 -(BAE)-C 12 and sodium polyelectrolyte polyacrylate (NaPAA) was investigated by surface tension, micropolarity and turbidity measurements. The results showed that there was a strong interaction between them. The aggregates were formed by electrostatic attraction between the molecules of C 12 -(BAE)-C 12 and NaPAA in the bulk. This process led to the appearance of two inflection points, the critical aggregation concentration ( cac ) and the critical micelle concentration (CMC), on the surface tension and micropolarity curves. In addition, the inorganic salt NaBr had two opposite effects, promoting or inhibiting the interaction between C 12 -(BAE)-C 12 and NaPAA. This was related to the concentration of NaBr itself.
