Mixed Cationic Surfactant Vesicles in (Dioctadecyldimethylammonium Bromide)/NaCl and (Dioctadecyldimethylammonium Chloride)/NaBr Aqueous Dispersions

One of the most challenging characteristics not fully understood yet of the cationic surfactant salt dioctadecyldimethylammonium (DODA + ) halide is concerned with the effects of the counterion (usually Br − and Cl − ) on the surfactant assembly into vesicle structures in aqueous solution. These counterions play a key role in the self‐organization of DODA + into bilayer structures. Differential scanning calorimetry (DSC) and dynamic light...
