In this work we studied and compared the physicochemical properties of the catanionic mixtures cetyltrimethyl-ammonium bromide-sodium dodecanoate, cetyltrimethyl-ammonium bromide-sodium perfluorodacanoate, octyltrimethylammonium bromide-sodium perfluorodacanoate and cetyltrimethyl-ammonium bromide-sodium octanoate by a combination of rheological, transmission electron microscopy (TEM) and polarized optical microscopy measurements. The binary mixtures of the surfactants have been analyzed at different mixed ratios and total concentration of the mixture. Mixtures containing a perfluorinated surfactant are able to form lamellar liquid crystals and stable spontaneous vesicles. Meanwhile, system containing just hydrogenated surfactants form hexagonal phases or they are arranged in elongated aggregates.
在这项工作中，我们通过流变学、透射电子显微镜（TEM）和偏光显微镜测量相结合的方法，研究并比较了阳离子混合胶束十六烷基三甲基溴化铵-十二酸钠、十六烷基三甲基溴化铵-全氟代癸酸钠、辛基三甲基溴化铵-全氟代癸酸钠和十六烷基三甲基溴化铵-辛酸钠的物理化学性质。研究了不同混合比例和混合物总浓度下表面活性剂的二元混合物。含有全氟表面活性剂的混合物能够形成层状液晶和稳定的自发囊泡。同时，仅含有氢化表面活性剂的体系形成六方相或排列成伸长的聚集体。
