It is known that electrical charge of a surfactant distributes along the molecule including the hydrophobic tail. The charge distributions of some hydrogenated/fluorinated surfactant molecules have been estimated by semiempirical quantum chemical methods PM3. The relationships between the charge distribution and the physico-chemical properties of surfactant systems, in particular the mixed surfactant...
Interactions between poly(ethylene oxide) (PEO), and equimolar mixed sodium decylsulfonate and decyltriethylammonium bromide were studied using surface tension, fluorescence, dynamic light scattering and freeze-fracture transmission electron microscopy techniques. Below the cmc of the equimolar mixed cationic–anionic surfactants, no obvious interaction was observed under the experimental conditions...
The interactions between sodium alkyl sulfates (C n SO 4 )/sodium alkyl sulfonates (C n SO 3 ) and polyethylene oxide (PEO) were studied by surface tension, fluorescence and dynamic light scattering measurements, assisted with quantum-chemical calculations. It was found that, although many properties of C n SO 4 and C n SO 3 were similar,...
