摘　　要：论述了超临界CO2微乳体系的基本原理,重点对表面活性剂在超临界CO2中形成微乳的机制进行了总结。同时介绍了超临界CO2微乳体系在金属离子萃取、生物活性分子的提取、化学反应、合成纳米材料及染色等方面的应用,并展望了该技术的发展趋势。The basic principle of supercritical carbon dioxide （SC-CO2 ） microemulsion and its development were reviewed in this paper, Meanwhile, the structure and properties of surfactants, which can form supercritical carbon dioxide microemulsions were also introduced. Moreover, the application of SC-CO2 microemulsions to the field of extraction of biochemicals and metal ions, chemical reaction, synthesis of nanomaterials and dying were also discussed. The prospect of SC-CO2 microemulsions was proposed.
