Abstract
AOT micelle formation in ethylammonium nitrate (an ionic liquid) was investigated by surface tension measurement in this article and the critical micelle concentrations (cmc) of AOT in ethylammonium nitrate at different temperatures were obtained. The thermodynamic parameters of micelle formation were obtained according to the two-phase thermodynamic model. The results suggested that the micelle formation of AOT in ethylammonium nitrate was a spontaneous, endothermal and entropy-increasing process.
