The liquid structures of six choline carboxylate/amino acid ionic liquids (bio-ILs) and their mixtures with water and various n-alkanols have been investigated by small-angle X-ray scattering (SAXS). The ILs exhibit long-range amphiphilic nanostructure comprised of polar and apolar domains that can be controlled by choice of anion, and which is tolerant to water dilution. Mixtures with n-alkanols can lead to marked changes in domain size and ordering. Utilising the Teubner-Strey model, we find amphiphilicity factors in many of these mixtures are comparable to those observed in conventional microemulsions, and that cooperative assembly in bio-IL/alkanol mixtures can enhance amphiphilicity, with potential to improve performance in a range of applications.
六种胆碱羧酸盐/氨基酸离子液体（生物离子液体）及其与水和各种正烷醇的混合物的液体结构已通过小角 X 射线散射（SAXS）进行了研究。这些离子液体表现出由极性和非极性域组成的长程两亲性纳米结构，可通过选择阴离子进行控制，并且能够耐受水稀释。与正烷醇的混合物会导致域大小和有序性发生明显变化。利用 Teubner-Strey 模型，我们发现许多这些混合物中的两亲性因子与在传统微乳液中观察到的那些相当，并且生物离子液体/正烷醇混合物中的协同组装可以增强两亲性，有可能改善一系列应用中的性能。
