Insight into the Hydration of Cationic Surfactants: A Thermodynamic and Dielectric Study of Functionalized Quaternary Ammonium Chlorides.

ABSTRACT: Hydrophobic interactions are one of the main thermodynamic driving forces in self-assembly, folding, and association processes. To understand the dehydration-driven solvent exposure of hydrophobic surfaces, the micellization of functionalized decyldimethylammonium chlorides, XC₁₀Me₂N⁺Cl^-, with a polar functional group, X = C₂OH, C₂OMe, C₂OC₂OMe, C₂OOEt, together with the "reference" compound decyltrimethylammonium chloride, C₁₀Me₃N⁺Cl^-, was investigated in aqueous solution by density measurements, isothermal titration calorimetry (ITC), and dielectric relaxation spectroscopy (DRS). From the density data, the apparent molar volumes of monomers and mi
