| 摘 要： | 通过粘度、电导率、表面张力以及紫外吸收光谱等手段,研究水溶性中性聚合物聚乙烯醇(PVA)与阳离子表面活性剂十六烷基三甲基溴化铵(CTAB)之间的相互作用。结果表明,PVA与CTAB之间有一定的相互作用,从而使体系表现出异常的粘度行为,显示出一定的电粘效应,并导致其混合溶液的最大紫外吸收峰发生了红移,未观察到PVA的加入对CTAB溶液表面张力和临界胶束浓度的影响。

| Abstract: | Interactions between a cationic surfactant, cetyltrimethyl ammonium bromide ( CTAB) and a water- soluble polymer polyvinyl alcohol (PVA) were investigated by means of viscosity, electric conductance, surface tension and ultraviolet spectra (UV) . Results show that PVA displays a special viscosity behavior in aqueous solution containing the surfactant CTAB, which is due to the molecular interaction of the polymer and the surfactant. In addition, solution of the surfactant CTAB shows unusual behaviors in electric conductivity and ultraviolet spectra (UV) in the presence of PVA, but no effects of PVA on surface tension and critical micelle concentration (cmc) of the surfactant were observed . |
