Evidence of self-aggregation of cationic surfactants in a choline chloride+glycerol deep eutectic solvent

Journal Contribution - Journal Article

Based on fluorescence probe, electrical conductivity, surface tension, small-angle X-ray/dynamic light scattering, and transmission electron microscopy experiments, we present the first clear lines of evidence for self-aggregation of cationic surfactants of the n-alkyltrimethylammonium family within an archetypical deep eutectic solvent comprised of a 1:2 molar mixture of choline chloride and glycerol. Estimated thermodynamic parameters suggest this self-aggregation process to be less entropically driven than that in water. These novel water-free self-assemblies might serve as dynamic soft templates to direct the growth of size- or shape-tailored nanoparticles within water-restricted media.
