摘要：

A surface active ionic liquid (IL), [CH3(CH2)(10)NH3][OOCCH3], was synthesized and characterized by FTIR, H-1 NMR, and C-13 NMR. Its surface activity and aggregation behavior in aqueous solution were investigated using surface tension measurements, conductivity measurements, transmission electron microscopy (TEM), and dynamic light scattering (DLS). The results reveal that the CAC and gamma(cac) of this IL are 15.3mM and 23.1 mN/m, respectively. We observed a strong interaction between the counter-ions, leading to ion pairs that self-assemble into spherical vesicles in aqueous solution, with an average diameter in the range of 120 to 130nm.
