The transition of rodlike micelles to wormlike micelles of an ionic liquid surfactant induced by different additives and the template-directed synthesis of calcium oxalate monohydrate to mimic the formation of urinary stones

The viscoelastic wormlike micelles composed of the ionic liquid surfactant, 1-hexadecyl-3-octyl imidazolium bromide ([C 16 imC 8 ]Br), and the β-cyclodextrin (β-CD) were utilized to mimic the formation of lithangiuria, that is the calcium oxalate monohydrate (COM). The influence of different additiv...

Description
Summary:The viscoelastic wormlike micelles composed of the ionic liquid surfactant, 1-hexadecyl-3-octyl imidazolium bromide ([C 16 imC 8 ]Br), and the β-cyclodextrin (β-CD) were utilized to mimic the formation of lithangiuria, that is the calcium oxalate monohydrate (COM). The influence of different additives, such as CaCl 2 and Na 2 C 2 O 4 (precursors for the synthesis of COM) and the β-CD on the viscoelasticity of the [C 16 imC 8 ]Br solution, was studied by the rheology. The [C 16 imC 8 ]Br rod-like micelles transit to the wormlike micelles induced by different additives. The [C 16 imC 8 ]Br/β-CD wormlike micelles containing the [C 16 imC 8 ]Br/β-CD inclusion complexes were characterized by the small angle X-ray scattering, surface tension measurements, zeta potential measurements, and cryo-TEM. The COM particles were synthesized in the [C 16 imC 8 ]Br/β-CD wormlike micelles which were characterized by the transmission electron microscopy and X-ray diffraction. The β-CD has important influence on the formation of COM. In the end, the mechanism of the synthesis of COM in the [C 16 imC 8 ]Br/β-CD wormlike micelles is proposed. Graphical abstract
