Gemini表面活性剂的研究进展及应用

Development and Application of Gemini Surfactants

Gemini表面活性剂是一类含有双疏水基双亲水基的新型表面活性剂,表面活性高,临界胶束浓度低,Krafft点低,因此在增溶、杀菌、制备新材料等方面具有广阔的应用前景。本文综述了Gemini表面活性剂的研究进展、性能及应用,指出了今后的发展趋势。

Gemini surfactants are reputed as a new generation of surfactants which have two hydrophobic chains and two hydrophilic heads.They have many properties such as high surface activity,low CMC and low Krafft point.So they have bright application foreground in the solubilizer,antibactericide,new materials and other industrial fields.The development,properties and application of Gemini surfactants were summarized in this paper.And the development trends are also pointed out.
