Model-Free Analysis of Critical Micellar Concentrations for Detecting Demixing in Surfactant Mixtures

摘要: Aqueous mixtures of two or more surfactants are often employed for research industrial purposes because such offer advantages over single-surfactant systems. This is particularly true fluorocarbon (FC) and hydrocarbon (HC) surfactants, which display a broad range mutual miscibilities in mixed micelles. Unfortunately, the prediction even experimental elucidation micellar mixing behavior surfactant remain challenging, as evidenced by conflicting results conclusions derived from diverse, complex, models. One most intriguing questions whether certain combinations FC HC form only one type micelle rather demix into populations, namely, FC-rich HC-rich ones. Here, we demonstrate novel approach to model-free analysis critical concentrations (CMCs) that based on fit data with cubic splines using stringent thermody...
