摘要
双疏水基双亲水基表面活性剂独特的分子结构使其具有与传统的单疏水基单亲水基表面活性剂不同的特性 ,如cmc很低 ,降低水溶液表面张力的效率很高 ,与非离子表面活性剂有更高的协同效应。着重介绍了该表面活性剂的结构特点 ,以及分子结构对其水溶液物化性能的影响。
Gemini surfactants have two hydrophobic groups and two hydrophilic groups per molecule.Comparing to conventional surfactants which have single hydrophobic group and single hydrophilic group per molecule,the distinct molecular structure of Gemini surfactants make them possess some special properties,such as quite lower surface tension and higher efficiency for reducing surface tension.By reviewing some authors reports,this article chiefly studied Gemini surfactants molecular structure and relationship between structure and property in aqueous media.
