摘要: 采用动态光散射、吸收光谱、粘度及电镜透射等方法研究了烷基氯化铵在弱碱性条件下溶液浓度变化对分子有序组合体结构的影响.当表面活性剂浓度大于cmc时,分子有序组合体的形态随表面活性剂浓度的增加出现胶团-囊泡-球状胶团的转化过程,这与水解产生的极性有机物烷基胺量的变化密切相关.

关键词: 烷基氯化铵, 分子有序组合体, 胶团, 囊泡

Abstract: The influences of concentration variation of the aqueous solution of C12 H25 NH3Cl on the molecular-ordered organized assemblies were studied by dynamic light scattering, absorption spectrometry, viscosity and TEM. It is found that the transition process of the micelles vesicles spherical micelles for the morphology of the molecular-ordered organized assemblies took place with the increase of surfactant concentration. Such structure transition can be attributed to the variation of concentration of hydrolytic product C12 H25 NH2.
