摘要/Abstract

摘要：

本文合成了含酰胺基团和不含酰胺基团的两类Gemini阳离子表面活性剂,测定了其表面活性参数,研究了酰胺基团对表面活性剂的表面活性和聚集行为的影响。结果表明,酰胺基团提高了Gemini阳离子表面活性剂的临界胶团浓度,降低了胶团聚集数,增强了胶团微极性,增大了表面活性剂的饱和吸附量。

关键词: Gemini表面活性剂, 表面活性, 聚集行为, 酰胺基团, 荧光探针

Abstract:

Amide groups are usually introduced in the molecular structures of surfactants to improve their biodegradability. In this paper, the Gemini cationic surfactants with/without amide were synthesized and their properties were measured. The effect of the amide group on the surface properties and aggregation behavior of the Gemini cationic surfactants was investigated. When amide groups are introduced in the molecules of the Gemini cationic surfactants, the values of cmc, Г_max and the micelle microviscosity increase and N_agg value decreases. It is concluded that hydrogen bonding between amide bonds contributes to the adsorption process of the surfactants at the surface of the solution.

Key words: Gemini surfactant, surface property, aggregation, amide group, fluorescence
