低共熔溶剂已显示出促进溶液中表面活性剂自组装的能力。然而，与纯水和其他极性有机溶剂中的自组装相比，发现了一些差异。通过表面张力、X射线和中子反射率以及小角中子散射研究了烷基三甲基溴化铵在氯化胆碱:甘油低共熔溶剂中的行为。发现表面活性剂保持表面活性，并显示出与水中相同表面活性剂相当的临界胶束浓度。我们的散射研究表明，这些表面活性剂在溶液中形成椭圆形的球状胶束。发现聚集体的尺寸、形状和聚集数量随表面活性剂的链长而变化。该系统中没有发现特定的溶剂-头基相互作用，这与我们之前假设的氯化胆碱低共熔溶剂中阴离子表面活性剂的相互作用不同。
Deep eutectic solvents have shown the ability to promote the self-assembly of surfactants in solution. However, some differences have been found compared with self-assembly in pure water and other polar organic solvents. The behaviour of alkyltrimethylammonium bromides in choline chloride:glycerol deep eutectic solvent has been studied by means of surface tension, X-ray and neutron reflectivity and small-angle neutron scattering. The surfactants were found to remain surface active and showed comparable critical micelle concentrations to the same surfactants in water. Our scattering studies demonstrate that these surfactants form globular micelles with ellipsoidal shape in solution. The size, shape and aggregation number of the aggregates were found to vary with the chain length of the surfactant. Specific solvent-headgroup interactions were not found in this system, unlike those we have previously postulated for anionic surfactants in choline chloride deep eutectic solvents.
