With perfluorooctanesulfonyl fluoride as raw material,a polyether quaternary ammonium salt cationic fluorocarbon surfactant was synthesized.Structures of the surfactant and its intermediates were characterized by IR and ¹H NMR spectroscopies.The surface tension of the surfactant in aqueous solution was measured,the lowest surface tension was 18.8 mN/m,and its critical micell concentration (CMC) was 54 mmol/L.This indicates it has a better surface activity than that of common surfactants.
- cationic fluorocarbon surfactant,
- polyether,
- quaternary ammonium salt,
- critical micelle concentration
