Conformation and Aggregation Behavior of Polyelectrolyte with Primary Amino Pendant Groups in Water or THE/Water Binary Solvent Mixture and Their Effect on the Morphology of AOT Vesicles in Aqueous Media

摘要

Cationic polyelectrolyte with primary amine pendant groups, poly (4-vinyl benzyl amine hydrochloride salt) (poly (4-VBAHS)), was characterized by static light scattering. Using light scattering measurement, the conformation transition of poly (4-VBAHS) chains in pure water, and THE/H_2O (v/v: 113) binary solvent mixture was discussed. Concentration-dependent multiple morphologies including interpenetrating networks, tubular micelles, branched micelles, hexagonal phases, vesicles, and needle crystals were observed by TEM. In addition, effect of poly (4-VBAHS) on the morphology, stability, and critical vesicle/micelle concentration of anionic surfactant sodium bis (2-ethylhexyl) sulfosucciante vesicles were detected using dynamic light scattering, zeta potential, surface tension, and transmission measurements.
