Supercritical (sc) CO2 and ionic liquids (ILs) are very attractive green solvents with tunable properties. Using scCO2 and ILs as alternatives of conventional solvents (water and oil) for forming amphiphile self-assemblies has many advantages. For example, the properties and structures of the amphiphile self-assemblies in these solvents can be easily modulated by tuning the properties of solvents; scCO2 has excellent solvation power and mass-transfer characteristics; ILs can dissolve both organic and inorganic substances and their properties are designable to satisfy the requirements of various applications. Therefore, the amphiphile self-assemblies in scCO2 and ILs have attracted considerable attention in recent years. This review describes the advances of using scCO2 or/and ILs as amphiphile self-assembly media in the last decade. The amphiphile self-assemblies in scCO2 and ILs are first reviewed, followed by the discussion on combination of scCO2 and ILs in creating microemulsions or emulsions. Some future directions on the amphiphile self-assemblies in scCO2 and ILs are highlighted.
超临界（sc）二氧化碳和离子液体（ILs）是极具吸引力的绿色溶剂，其性质可调。使用scCO₂和离子液体作为传统溶剂（水和油）的替代品来形成两亲性自组装体具有诸多优势。例如，通过调节溶剂性质，可轻松调控这些溶剂中两亲性自组装体的性质和结构；scCO₂具有出色的溶解能力和传质特性；离子液体既能溶解有机物质又能溶解无机物质，并且其性质可设计以满足各种应用的需求。因此，近年来scCO₂和离子液体中的两亲性自组装体受到了相当大的关注。本综述描述了过去十年中使用scCO₂或/和离子液体作为两亲性自组装介质的进展。首先综述了scCO₂和离子液体中的两亲性自组装体，接着讨论了scCO₂和离子液体在形成微乳液或乳液方面的组合。最后强调了scCO₂和离子液体中两亲性自组装体未来的一些发展方向。
