摘要:

双子表面活性剂是一种具有两个亲水基团、两条疏水链和一个联接基团的新型表面活性剂。与传统的表面活性剂相比,双子表面活性剂具有较低的临界胶束浓度、较高的表面活性、高效降低水的表面张力和油/水界面张力以及良好的水溶性等特点。双子表面活性剂广泛应用于抑菌、灭菌、食品生产、消泡抑泡、药物缓释以及工业清洗等领域,对推动社会、经济、工业的进步有着非常重要的积极作用。本文简要概括了双子表面活性剂的发展,介绍了双子表面活性剂的活性和组装结构,对双子表面活性剂的分类、结构和特征进行了概括和总结。

Abstract:

Gemini surfactants contain two hydrophilic and two hydrophobic groups connected by a linkage close to the hydrophilic groups. Gemini surfactants have lower critical micelle concentration, higher surface activity, greater efficiency in decreasing the surface tension of water and the interfacial tension between water and oil, and better water solubility than conventional surfactants. Gemini surfactants are widely used as sterilizing, bacteriostatic, anti-foaming, and drug release agents in various enterprises including food production and industrial cleaning. They, therefore, play a very important social, economic, and industrial role. This paper briefly summarizes gemini surfactant development, structure, self-assembly, activity, classification, and characteristics, as well as focuses on the antibacterial mechanisms of these compounds. It is expected that the antibacterial properties of gemini surfactants may help slow the spread of the novel coronavirus (2019-nCoV).

Key words: Gemini surfactants, Antibacterial, 2019-nCoV
