摘要：

合成了基于胱氨酸的两种Gemini表面活性剂, N,N’-二对丁氧基肉桂酰胺基胱氨酸钠(SDBCC)和N,N’-二癸酰胺基胱氨酸钠(SDDC). 利用表面张力、动态光散射(DLS)、透射电镜(TEM)等手段研究了体系的表面性质和聚集行为.

关键词: Gemini型两亲分子, 表面性质, 囊泡, 聚集行为

Abstract:

Two amino acid-based Gemini surfactants derived fromcystine, sodium N,N’-di(4-n-butyloxycinnamoly)-L-cystine (SDBCC) and sodium N,N’-didecamino L-cystine (SDDC), were synthesized. Their surface activity and aggregation properties were also investigated by equilibrium surface tension measurements, dynamic light scattering (DLS), and transmission electron microscopy (TEM).

Key words: Gemini surfactant, Surface activity, Vesicle, Aggregation behavior
