Surfactant self-assembly in mixed choline chloride:urea-choline chloride:glycerol deep eutectic solvents

Abstract: 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 makes 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. We found that cationic surfactants were not soluble in choline chloride:urea DES, yet urea plays an active role in synthesis of inorganic oxides via decomposition, and this also degrades anionic surfactants in DES so they cannot act as templates. Cationic surfactants are soluble, and anionic surfactants suffer less decomposition, in mixtures of choline choride:urea-choline chloride:glycerol DES, so here we plan to study CnTAB and SDS micelles in this mixed solvent.
