“…This leads to low solubility of amphiphilic molecules in solution, thereby reducing the tendency of micellization with the increase in temperature. The increase in the value of cmc with elevating temperature is consistent with the literature (Chaudhary and Pal, 2014; Pal et al, 2015; Pal and Saini, 2020).…”

Mixed micellization behavior of dodecyl sulfate‐based ionic liquids, i.e., 1‐propyl‐3‐methylimidazolium dodecyl sulfate [C3mim][DS] and 1‐hexyl‐3‐methylimidazolium dodecyl sulfate [C6mim][DS] with sodium dodecyl sulfate (SDS), is investigated at (298.15, 308.15, and 318.15) K in aqueous medium. For this, the conductometric measurements are carried out to evaluate the critical micelle concentrations (cmc), ideal critical micelle concentration (cmc*), degree of counterion dissociation (g), thermodynamic parameters, micellar mole fraction of ionic liquids, and interaction parameter (β) of the mixed system based on the different proposed models given in the literature. Further surface tension measurements have been carried out to confirm the value of cmc obtained via a conductivity study for all the studied systems at 298.15 K. Other surface parameters, such as surface tension at cmc (γcmc), surface pressure (ᴨcmc), surface excess (Γmax), and minimum area per molecule (Amin), have also been evaluated for both the systems.

“…As a consequence, the micellization tendency is reduced, and the cmc of solutions at higher temperatures is increased. This rise in cmc with increasing temperature is in line with previous research (12,13). The variations in thermodynamic parameters of micellization with temperature as well as mole fraction have been shown in Figure 4.…”

The investigation of mixed micellar behavior of surface-active ionic liquid (SAIL) i.e. 1-butyl-3-methylimidazolium hexadecyl sulfate [C4mim][HS] with cationic surfactant cetyltrimethylammonium bromide (CTAB) has been done to explore the type of interactions prevailing in SAIL/Surfactant mixed system. Thus, the conductometric measurements are performed at (298.15, 308.15 and 318.15) K for various mole fractions of [C4mim][HS]. Different theoretical models like Clint, Rubingh, Motomura and Rodenas have been applied to understand mixed micellar behavior of SAIL/Surfactant mixed system. The value of critical micelle concentrations (cmc), micellar mole fraction based upon various models, ideal critical micelle concentrations (cmc*), interaction parameter (β) and thermodynamic parameters have been evaluated for the mixed systems. The variations of various parameters with respect to temperature and mole fractions give insight to sort of interactions present in studied system.

“…Pal and Saini ( 2020 ) synthesized and characterized SAILs having 1-alkyl-3-methylimidazolium cationic moiety and dodecyl benzenesulfonate-based anionic moiety i.e., [C 5 mim][DBS] and [C 7 mim][DBS]. They investigated their aggregation behavior by using conductivity, surface tension measurements, UV-visible and fluorescence spectroscopic techniques, and determined their value of CMC, thermodynamic parameters as well as surface-active parameters.…”

The desire of improving various processes like enhanced oil recovery (EOR), water treatment technologies, biomass extraction, organic synthesis, carbon capture etc. in which conventional surfactants have been traditionally utilized; prompted various researchers to explore the self-assembly and aggregation behavior of different kinds of surface-active molecules. Ionic liquids (ILs) with long alkyl chain present in their structure constitute the advantageous properties of surfactant and ILs, hence termed as surface-active ionic liquids (SAILs). The addition of ILs and SAILs significantly influence the surface-activity and aggregation behavior of industrially useful conventional surfactants. After a brief review of ILs, SAILs and surfactants, the prime focus is made on analyzing the self-assembly of SAILs and the mixed micellization behavior of conventional surfactants with different ILs.
