Physicochemical Understanding of Self-Aggregation and Microstructure of a Surface-Active Ionic Liquid [C₄mim] [C₈OSO₃] Mixed with a Reverse Pluronic 10R5 (PO₈EO₂₂PO₈).

ABSTRACT: Physicochemical studies on aqueous mixtures of ionic liquids (ILs) and reverse pluronics are limited. Self-aggregation dynamics and microstructure of a surface-active IL (SAIL), 1-butyl-3-methylimidazolium octylsulfate [C₄mim] [C₈OSO₃], in the presence of a reverse pluronic, PO₈EO₂₂PO₈ (known as 10R5), were studied using isothermal titration calorimetry (ITC), high-resolution nuclear magnetic resonance (NMR), and small-angle neutron scattering (SANS) methods. Also, cryo-/freeze-fracture transmission electron microscopy was employed to determine the microstructures of SAIL/10R5 mixtures. The ITC and NMR results revealed facilitation of SAIL aggregation in the presence of 10R5 forming mixed aggregates as well as free SAIL mice
