几种聚氧乙烯醚型表面活性剂的表面活性比较研究

摘要

The equilibrium and dynamic surface tension, critical micel e concentration (cmc) of the four kinds of nonionic polyoxyethylene ether surfactants in market were measured and compared. The results showed that the type and structure of the hydrophobic group in surfactant had important influence on the equi?librium surface tension and dynamic surface tension.%选取了4种聚氧乙烯醚型非离子表面活性剂,测试了其平衡态和动态表面性能,并进行对比研究.结果表明:表面活性剂中疏水基的种类、构型对其平衡态和动态表面张力有重要影响.
