Scrutinizing Self-Assembly, Surface Activity and Aggregation Behavior of Mixtures of Imidazolium Based Ionic Liquids and Surfactants: A Comprehensive Review

Abstract: 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 surf… Show more

“…At this point, the surface tension value is constant. In fact, this is the common behavior of surface active ionic liquids that can adsorb at the liquid–air interface [ 32 ]. To investigate the surface activity of imidazolium ionic liquids, we used parameters such as critical micelle concentration (CMC), surface tension at the CMC (γCMC), maximum excess concentration (Γ max ), free energy change of adsorption (ΔG 0 ads ), and area per molecule residing at the surface (A min ).…”

“…Also, amphipathic ILs have been developed that are miscible in a wide range of solvents and display surface activity (surface-active ILs, or SAILs), representing a new class of surfactants, some of which possess interesting biological properties, such as antimicrobial action. Relevantly, though emerging from the 2nd generation of ILs for applications as, e.g., emulsifiers, SAILs enclose a tremendous potential for biomedical and pharmaceutical applications [ 14 , 126 , 127 ].…”

“…Such behavior could lead to a critical hydrate inhibition and/or promotion effect with increasing change length. Also, long alkyl chain length ILs form micelles due to their surfactant-like behavior which could consequently diminish their thermodynamic hydrate inhibition impact. Typically, ammonium cation groups have been reported to exhibit such properties, especially with bromide anion .…”
