摘要:
离子液体表面活性剂替代传统表面活性剂构建微乳液具有明显的优势,且结构可设计;所制备的微乳液分为单相微乳液和多相微乳液,其相图主要包括拟三元相图和“鱼状”相图;微乳液的微观结构,如液滴尺寸、相互作用或极性等,可通过电化学技术、动态激光散射、小角X射线散射等技术来确定。此类微乳液可广泛应用于纳米粒子制备、聚合反应、金属离子萃取等领域。

Abstract:
Ionic liquid surfactants show obvious advantages over traditional surfactants in the construction of microemulsions and the structure can be designed purposely according to the requirement. The prepared microemulsions can be classified as singlephase microemulsions and multiphase microemulsions, for which the phase diagrams mainly cover pseudo ternary phase diagrams and “fish-like” phase diagrams. The microstructure of microemulsions, such as droplet size, interaction or polarity, can be determined by electrochemical techniques, dynamic laser scattering, small angle X-ray scattering and so on. Ionic liquid surfactant microemulsions can be widely used in the fields of nanoparticle preparations, polymerization, metal ion extraction, etc.
Key words:  surfactant  ionic liquid  phase diagram  microstructure  application
