Interfacial Properties of Aggregates Formed by Cationic Polyelectrolyte and Anionic Surfactant

摘要: Interactions between mica surfaces across aqueous solutions containing mixtures of a highly positively charged polyelectrolyte and an anionic surfactant were studied by use surface force apparatus. The investigation was carried out with constant concentration (20 ppm) wide range concentrations [0−1 times the critical micelle (cmc)]. chemical composition adsorbed polyelectrolyte-surfactant layers analyzed x-ray photoelectron spectroscopy (XPS). properties aggregates formed in bulk measurements turbidity electrophoretic mobility. at low (<0.04 cmc) charged, whereas higher net negative charge. It shown that polyelectrolyte−surfactant rapidly adsorb on negatively regardless sign their At conce...
