摘　　要：采用阴离子表面活性剂十二烷基苯磺酸钠与阳离子表面活性剂十二烷基三甲基氯化铵复配,在合适的比例自发形成囊泡。考察了形成囊泡的复配比例,发现温度升高和滴加有机溶剂都会使囊泡稳定时间更长,通过粒度分析仪检测囊泡的平均粒径在140nm左右,并且囊泡大小均匀。The formation and stability of vesicles from the mixture of anionic surfactant sodium dodecylbenzene sulfonate and dodecyl trimethyl ammonium chloride were studied. Vesicles can spontaneously form in systems of anionic and cationic surfactant. The proportion of two surfactants to form vesicle was investigated, and the effect of temperature and organic solvent on vesicle′s stability was discussed.
