| 摘 要： | 利用荧光探针法研究了双子型阳离子表面活性剂与明胶的相互作用,考察了此类表面活性剂的分子结构和明胶对临界胶团浓度(cmc)、胶团聚集数(Nagg)和胶团微极性的影响.结果表明,当双子型阳离子表面活性剂的疏水基增长时,cmc减少,Nagg增加,胶团的微极性降低;加入明胶后,双子型阳离子表面活性剂的Nagg减少,cmc和胶团微极性增加.

| Abstract: | Steady-state fluorescence has been used to investigate the interaction between Gemini cationic surfactants and gelatin.The critical micelle concentration,micelle aggregation number and micelle micropolarity of Gemini cationic surfactants have been determined.With increasing of the hydrophobic group of the Gemini cationic surfactants,the cmc and the micelle micropolarity decrease,Nagg increases.Addition of gelatin has the effect on the micelles of the Gemini cationic surfactants: the cmc value and the micelle micropolarity increase,Nagg decreases. |
