Complex by Design: Hydrotrope-Induced Micellar Growth in Deep Eutectic Solvents
Adrian Sanchez-Fernandez, Anna E. Leung, Elizabeth Kelley, Andrew J. Jackson
Here the microstructure of hydrotrope-surfactant assemblies in 1:2 choline chloride:glycerol (ChCl:Glyc) is presented. The effect of choline salicylate (ChSal) on the micellization of hexadecyltrimethylammonium chloride (C16TAC) was investigated by contrast-variation small-angle neutron scattering (SANS). The microscopic characterization of the system shows that the micelle-hydrotrope interaction in pure and hydrated deep eutectic solvents (DES) results in a significant increase in micelle elongation, leading to the formation of worm-like micelles (WLM) with tunable morphology and flexibility. The results presented here open new possibilities in terms of self-assembly and co-assembly in neoteric solvents, where micelle morphology can be controlled through surfactant-hydrotrope interactions.
