“…Therefore, this kind of system, with the advantages of both ILs and ordered microstructure, has recently become a research hotspot, 18,19 and the research on their microstructure transition and characteristics can be of sustained interest for their various applications. 20 It is the first time that Reinsborough and Bloom reported the amphiphilic self-assembled system, the molten salt of pyridinium chloride, with a melting point of 146 °C. 21 The first use of ILs in self-assembled systems was the formation of micelles in ethylammonium nitrate reported by Evans et al in 1980s.…”

“…The introduction of surfactants helps in the formation of self-assembled systems (such as micelles , and microemulsions) in ILs, which not only overcomes that limitation but enriches the traditional ordered molecular aggregates.

Dielectric relaxation spectra of ([Bmim][BF]/TX-100/ p-xylene) microemulsions and ([Bmim][BF]/TX-100) micelles were measured. A specific dielectric relaxation changing with the concentration of ionic liquids (ILs) was observed in the range of 10-10 Hz. When dielectric parameters were combined with the Einstein displacement equation and Bruggeman's effective-medium approximation, the interaction between [Bmim][BF] and p-(1,1,3,3-tetramethylbutyl) phenoxypolyoxyethyleneglycol (TX-100) in microemulsions/micelles was presented: because of the electrostatic interaction and van der Waals force, [Bmim][BF] is bound around the polyethylene oxide (PEO) chains of TX-100, and once the electric field is added, ions of [Bmim][BF] will move along the PEO chain. The dependence of dielectric and phase parameters such as relaxation time, permittivity, and volume fraction on the mass fraction of ILs presents an evidence for our proposals about the transition of both systems with the increase of IL content. In addition, it was confirmed that percolation is a unique phenomenon in microemulsions and the percolation mechanism here belongs to static percolation. The transition process of micelles with the change of IL content is presented from the dielectric view.
