【Abstract】 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 authors reports,this article chiefly studied Gemini surfactants molecular structure and relationship between structure and property in aqueous media.更多还原
