Surface adsorption and aggregate formation of nonionic surfactants in a room temperature ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate (bmimPF6)

Studies on formation and percolation in ionic liquids/TX-100/water microemulsions

“…5. It was previously shown that the structural transitions from W/O to O/W in microemulsions with an addition of water, result in viscosity increase of the system, and may evidence maxima in the viscosity profiles [43,57,58]. Fanun, for example, observed two peaks in viscosity value dependence with increasing water volume fraction for water/sucrose laurate/ethoxylated monodi-glyceride/R (+)-limonene system, implying an existence of at least three microstructural regions [50].…”

Effect of [C n mim][Br] Based Ionic Liquids on the Aggregation Behavior of Tetradecyltrimethylammonium Bromide in Aqueous Medium

“…To knowledge, the first report on cationic surfactant self-assembly in a non-aqueous medium was published in 1967 [30]. The aggregation behavior of the ionic [19, 20, 25-29, 31, 33-38, 40], non-ionic [19,23,24,32,41] and zwitterionic [21,22] surfactants with a range of ILs having various cations and anions has been studied in detail. The effect of the hydrophobicity of the alkyl groups of the ILs and surfactant anions on the CMCs, size distributions and thermodynamics of micellization has also been investigated [27,34,35].…”

“…Physicochemical properties of aqueous cationic, anionic, non-ionic and zwitterionic surfactants such as the CMC, size of the aggregates, aggregation number, dipolarity and microfluidity have been systematically modified by adding ILs [21][22][23][24][25][26] 4 ] on the physicochemical properties of aqueous anionic and cationic surfactants [28,29,[36][37][38][39][40]. ILs composed of different cations and anions have been extensively studied by various research groups in the field of colloid and interface science and some extensive reviews are available [41][42][43][44][45][46][47][48].…”

The effect of hydrophilic ionic liquid 1-butyl-2,3-dimethylimidazolium bromide on the aggregation behavior of tetradecyltrimethylammonium bromide in aqueous media

“…From the past decade many research groups have invested efforts to utilize ILs to modify the properties of various surfactants [19][20][21][22]. Pandey et al have shown the effect of ILs on the aggregation behavior of different types of surfactants [23][24][25].…”
