【摘要】 双子表面活性剂(gemini或dimeric)是由两个单链单头基普通表面活性剂在离子头基处通过化学键联接而成,这种特殊的结构使其具有比传统表面活性剂更优的性能,本文介绍了双子表面活性剂的发展简史、研究概况以及结构特点,表明这种表面活性剂具有重要的实用价值。更多还原

【Abstract】 Gemini(or dimerie)surfactants are made up of two identical amphiphillic moieties eovalently connected at the level of the headgroups by a spacer group. Because of its especial structure, Gemini surfactants have better properties than average surfactants. In this essay, the development, general situation of research and structure features of Gemini are introduced. It is pointed out that Gemini surfaetants have important application in various industry field.更多还原
