摘要针对全氟长链(≥Cs)氟碳表面活性剂存在的生物降解性差的环保问题，以全氟己基为基础，设计合成了一种新型的短氟碳链双子氟表面活性剂，并利用表面张力方法考察了其室内性能。实验结果发现，该短氟碳链双子氟表面活性剂水溶性好，表面活性强，临界胶束浓度低至3.0义10-4~ 3.4X10-4mol/L.Ycmc=16.0mN/m：抗盐性能优异，在高矿化度条件下，仍具有较高的表面活性：抗温性能好，化学稳定性强能够适应高温、强酸强碱复杂环境；并且短氟碳链的氟表面活性剂对环境的伤害小，能够作为全氟长链氟表面活性剂的替代品，具有良好的应用前景。

Abstract: In order to solve the environmental problem of poor biodegradability of fluorocarbon surfactant with perfluorinated long chain (≥Cs ), a new type of short fluorocarbon gemini-fluoro surfactant was designed and synthesized in this paper on the basis of perfluoro hexyl , and its internal performance was studied by surface tension method . The results showed that the short fluorocarbon gemini.fluoro surfactant has good water solubility , strong surface activity , and the critical micelle concentration is as low as 3.0 X 104—3.4X104 mol/L and Yeme= 16 .0 mN/m ; it also has excellent salt resistance, and has high surface activity under high salinity condition ; it has good temperature resistance and chemical stability , and can adapt to high temperature , strong acid and alkali complex environment; and the short fluorocarbon chain fluorine surfactant has less damage to the environment, it can be used as a substitute of perfluorinated long chain fluorine surfactant , and has good application prospect
Key words : perfluorinated hexyl, short-fluorocarbon , gemini, high surface activity , environment friendly
