-
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.
