聚电解质对表面活性剂胶束形成的影响研究

The Effects of Polyelectrolyte on the Micelle Formation of Surfactant

采用粘度、电导率、可见光光度计以及荧光光谱方法研究了聚电解质与表面活性剂在水溶液中的静电相互作用和疏水相互作用．认为表面活性剂头基电荷的种类对二者的相互作用有极大影响．二者复合物沉淀的产生取决于表面活性剂是以分子状态还是以胶束状态进入聚电解质溶液中．同时发现在有聚电解质存在时。

The effects of poly (N ethyl 4 vinylpyridium bromide) on the formation of Sodium Dodecyl Sulfate were investigated based on viscosity, conductivity, visible photometer and fluorescence spectroscopy. It was found that the reduced viscosity of polyelectrolyte in the presence of oppositely charged anionic surfactant (SDS) was lower than that in the presence of cationic surfactant. The formation of polymer bound micelles depending on the surfactant was added in the form of either monomer or micelle. SDS micelles were formed by induced polyelectrolyte below the normal CMC in pure water.
