摘　　要：超临界微乳/反胶束体系极大地拓展了超临界流体的溶剂特性,是超临界流体技术研究的热点课题。选择合适的表面活性剂,通过调控操作条件,可以方便地控制其增溶特性,作为一种新兴绿色溶剂,在化学反应、材料制备、萃取分离等领域都有潜在的应用前景。本文阐述了超临界CO2微乳/反胶束系统的基本概念,总结和归纳了关于热力学性质、表面活性剂选择、相行为、水力学尺寸计算、聚团颗粒间相互作用力等理论研究成果。在此基础上,还就该领域的一些应用进行了分析讨论。Supercritical microemulsions （reverse micelle ） which improves the solvent properties of supercritical fluid greatly is a hot topic in the research of supercritical fluid technology. The solubilization behavior can be manipulated easily by choosing appropriate surfactants and controlling the operating conditions. As a new green solvent, it has large potential applications in many fields, such as chemical reactions, material preparations and extraction separations. This article provides information of the conceptions of supercritical microemulsions （reverse micelle） system and gives an overview of thermodynamics characteristics, selection of surfactants, phase behavior, calculation of hydrodynamic sizes and interdroplets interactions. The applications in these fields are also reviewed.
