摘要
自1989年Kaler等[1]在正负离子表面活性剂混合体系中制备了性质稳定的囊泡以来,正负离子表面活性剂体系以其特异的自组织行为受到了人们的关注.1994年肖进新等[2,3]报道了正负离子表面活性剂双水相的形成,并将其用于生物活性物质的萃取分离.
In this work a way of transition from precipitation to vesicle through addition of short chain fatty al-cohol was developed. By adding 7% - 14%(V/V) of 1-propanol or 10% - 21%(V/V) of ethanol at 30℃ the precipitation of catanionic surfactant was dissolved to give a two liquid-phase system. The photography of TEM demonstrated that vesicles exist in the lower phase. The phenomenon of double refraction was found in the upper phase.
