Anionic surfactant self-assembly in halide free deep eutectic solvents
Deep Eutectic Solvents (DES) are mixtures of organic salts and hydrogen bond donors, that form strongly hydrogen-bonded room temperature liquids. DES share many features with ionic liquids (ie. tunable physicochemical properties) which make them viable green solvents that are less toxic than typical ILs. We have studied amphiphile self-assembly in DES with the aim of developing templated deep eutectic-solvothermal syntheses for catalytic porous metal oxide structures, and have studied self-assembly in a range of choline chloride based DES. The halide anion however is known to poison many catalytic particles, so here we wish to probe surfactant self-assembly in a halide free DES, betaine:glycerol. We have previously studied a glycerol:citric acid solvent which supports micellization for cationic and nonionic surfactants, but not anionics. Betaine:glycerol in contrast solubilised anionic surfactants but not the others. We hypothesis that headgroup interactions with solvent components alter the solubility and self-assembly in these solvents and propose to use contrast variation SANS to better understand the structures formed in these solutions.
