Novel emulsions of ionic liquids stabilised solely by silica nanoparticles

Abstract

We have successfully prepared a series of novel stable emulsions, of both simple and multiple types, containing ionic liquids and stabilised solely by silica nanoparticles.

Use of ionic liquids in sol-gel; ionogels and applications

“…However, the surface modification of silica particles can afford the complete stabilization of dispersions in ILs, as recently shown with polymergrafted silica particles [29]. Note that emulsions of ionic liquids (both ionic liquid-in-water and ionic liquid-in-oil types) were reported, which were stabilized using fumed silica nanoparticles coated to different extents with hydrophobic methyl groups [33].…”

Structural studies of the phase, aggregation and surface behaviour of 1-alkyl-3-methylimidazolium halide + water mixtures

“…This expectation has led to a number of experimental and computer simulation studies of the bulk structure of pure ILs [15][16][17][18][19][20] and IL-containing mixtures [14,21]. The ability to form dispersed systems [22][23][24][25][26] and the potential for interfacial ordering has meant that understanding the interfacial properties of ILs and their mixtures is of increasing relevance [27]. Although studies of the surfaces of pure ILs has attracted theoretical [28,29] and experimental [30][31][32][33][34][35][36][37] interest, related studies of mixtures of ILs with other solvents are, however, rare, and of these most deal with aqueous mixtures only [14,38,39].…”

Microregion detection of ionic liquid microemulsions

“…As ideal alternative solvents, they have been widely applied to chemical reactions, separations, electrochemical applications, biopolymers, molecular self-assembly, and interfacial syntheses [4,9,10]. Moreover, ILs have been used to substitute for water or organic solvents to prepare novel IL microemulsions.…”
