In this work a way of transition from precipitation to vesicle through addition of short chain fatty alcohol 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.
