Abstract

Abstract: In the last few decades ionic liquids (ILs) have been widely considered as a "green solvents" and they are used in various fields. ILs can be used in the formation of microemulsion as a dispersed medium, polar domain and recently as a surfactant. In this particular review our discussion is about the novel IL-based aqueous and non-aqueous microemulsions which are quite fascinating and interesting research field for scientists. Synthesis of double and triple chain containing surface active ionic liquid (SAILs) and formation of microemulsion as a surfactant with ILs as a polar core have been elaborated in this review. ILs with a certain surface activity having long alkyl chain substituents can self-aggregate and form ILs microemulsion with high-temperature stability and temperature insensitivity. Characterization of these ILs in oil microemulsion and different ultrafast processes which are performed inside these characterized systems are documented very well. We have highlighted the similarities and differences between the nonaqueous microemulsions and the aqueous microemulsions. Addition of water and effect of temperature are quite important in case of the ILs containing microemulsions. Graphical abstract:
