| 摘 要： | 为建立文题所述模型,以微乳液的稳定性理论为基础,综合分析了表面活性剂分子在油-水界面上的缔合作用、界面膜弯曲时产生的附加能量、各种类型的混合熵以及表面活性剂分子和蛋白质分子的静电作用。所得模型正确地反映了含蛋白质的逆胶束系统稳定的原因,较好地描述了蛋白质转移后胶束大小的变化以及蛋白质转移率随电解质浓度变化的特殊的实验规律。

| Abstract: | Based on the stability theory of microemulsions, a title model has been established. Key factors considered are the association of surfactant molecules on the oil-water interface, extra energy caused by the bending of the surface membrane, and various entropies of mixing. Electrostatic interactions are also taken into account because of the charge characteristics of surfactant and protein molecules. The model presented can properly describe the size change of reverse micelles after the protein uptake. The experimental results of the protein transfer ratio as a function of salt concentrations can also be reproduced satisfactorily. |
