应用表面张力法、NMR法和ESR法研究了全氟辛酸钠(SPFO)-十二烷基三甲基溴化铵(DTAB)混合体系水溶液胶束形成及混合胶束的微环境性质(微观粘度、微观极性等).结果表明,碳氟表面活性剂碳氟链和碳氢表面活性剂碳氢链之间具有强烈的相互作用,DTAB与SPFO在水溶液中形成混合胶束.DTAB与SPFO混合体系的表面活性高于单一的DTAB或SPFO,混合体系cmc较单一的DTAB和SPFO低.DTAB与SPFO混合胶束的微观粘度较DTAB胶束的大,而微观极性较DTAB的小.
The micelle formation and the microenvironmental properties of the micelles were investigated by surface tension method, NMR method and ESR method. Polarity, etc.) .The results show that there is a strong interaction between fluorocarbon chain of fluorocarbon surfactant and hydrocarbon chain of hydrocarbon surfactant, and DTAB and SPFO form mixed micelles in aqueous solution.DTAB and SPFO mixed system The surface activity was higher than that of single DTAB or SPFO, and the mixed system cmc was lower than that of single DTAB and SPFO.The microviscosity of mixed micelles of DTAB and SPFO was larger than that of DTAB micelles, while the micro-polarity was smaller than that of DTAB.
