摘　　要：用表面张力法研究了AOT在硝基乙胺中形成的胶束聚集体,得到了在不同温度下AOT在硝基乙胺中形成胶束的临界胶束浓度,并根据胶束的两相模型的热力学方程得到了胶束形成的热力学参数,结果表明溶液中胶束的形成是一个自发,吸热,熵增大的过程。AOT micelle formation in ethylammonium nitrate （an ionic liquid） was investigated by surface tension measurement in this paper 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 twophase thermodynamic model. The results suggested that the micelle formation of AOT in ethylammonium nitrate was a spontaneous, endothermal and entropy - increasing process.
