双子表面活性剂有序聚集体的形成

Formation of self-assembled aggregates of gemini surfactant

综述了gemini(双子)表面活性剂的分子结构以及溶液的浓度、温度、pH值和反离子等因素对gemini表面活性剂聚集行为的影响。通过调整以上因素可以有目的地调控gemini表面活性剂有序聚集体的形成。这些有序聚集体不仅在生产和生活中有重要应用,而且与生命活动中的一系列现象密切相关,受到各个领域科学家的广泛重视。尽管gemini表面活性剂所形成的各种聚集体已经得到了广泛证实,但对形成的机理和实际应用的研究仍比较薄弱。

Effects of molecular structure as well as factors such as concentration of surfactant solution, temperature, pH value and counter ion on the self - assembling behavior of gemini surfactants were reviewed. Through changes of the above - mentioned factors, the formation of self - assembled aggregates can be adjusted and controlled purposely. Such self- assembled aggregates not only have important applications in industrial production as well as in personal life, but also correlated with a series of life activity phenomena. Nevertheless various self- assembled aggregates of gemini surfaetant have been well proven by experiments, the study on mechanism of their formation and their practical applications are not yet well developed.
