摘要:

表面活性剂分子是典型的两亲分子,由于其具有润湿、乳化、起泡、分散、增溶等多种性能,已在日化行业、食品工业、三次采油、细胞作用和酶效应领域得到广泛的研究及应用。表面活性剂分子具有两亲性,可以在非共价键弱相互作用的驱动下在溶液中自发形成各种有序聚集体结构。得益于有序聚集体的结构效应和尺寸效应,可以进一步拓展表面活性剂在离子传导方面的应用。这些有序聚集体可以为离子的传输提供连续的传导通道,进而大大提高离子的传导效率。

关键词: 表面活性剂, 弱相互作用, 自组装, 离子传导

Abstract:

Surfactants are one kind of typical amphiphilic molecules, which have been widely studied and applied in the fields of daily chemical industry, food industry, tertiary oil recovery, cell effect and enzyme effect due to their various properties such as wetting, emulsifying, foaming, dispersing and solubilizing. Driven by the non-covalent interactions, surfactant molecules can spontaneously form various ordered aggregate structures in solution. Owing to the structure effect and size effect of ordered aggregates, the application of surfactants in ion conduction has been extended. These ordered aggregates can provide a continuous conduction channel for ion transportation, which can greatly improve the ion-conducting efficiency.

Key words: surfactant, weak interaction, self-assembly, ionic conduction
