Abstract

Four new fluorocarbon surfactants were introduced, namely fluorocarbon sulfurous quaternary ammonium salt, fluorocarbon carboxylic betaine, 8-3-9 fluorocarbon-space-hydrocarbon Gemini surfactant,6-3-9 fluorocarbon-space-fluorocarbon Gemini surfactant, CMC of which are 1. 14×10-4 , 1. 12×10-3,4. 93×10-4 and 2.78 ×10-4 mol/L respectively. The surface tensions of the water solutions are 19. 0,22. 0,20. 9 and 22. 7 mN/m respectively at CMC, as well 16. 4,18. 2,19. 2 and 20. 4 mN/m respectively in 0.1% water solution. The relationship between the structure and property was illustrated in brief.
