The aggregation behaviors and thermodynamic properties of binary mixture of ionic liquid surfactant 1-hexadecyl-3-methy-limidazolium bromide( C16 mimBr) and nonionic surfactant Tween20 were investigated by surface tension measurements. Established theories of Rubingh and Maeda were applied to evaluate the mole fraction of different components,the interaction parameters and several thermodynamic properties in micellar phase. It was shown there was synergistic effect on mixed micelle formation. The con-centration of nonionic surfactant in the micelle phase was always higher than its bulk concentration. The driving force and stability of the micelle formation had been analyzed and discussed.
