The effect of mixed ratio and concentration on the spontaneous formation of vesicles in cationic cetyltrimethylammonium bromide (CTAB) and anionic sodium dodecylbenzenesulfonate (SDBS) system were investigated. The effect of Prepare method and aging time on the diameter of vesicles were also studied. TEM technique was used to observe the shape of vesicles and showed the phenomenon of the aggregation and fusing between vesicles. The result of Zetaplas also showed the diameter of vesicles increased with time. So, polymerization method was used to enhance the stability of vesciles and the results showed the diameter of polymerized vesicles less than unpolymerized.

Key words: Vesicle, Spontaneous Formation, Polymerization, Stability
