General description

Heptadecafluorooctanesulfonic acid potassium salt is commonly utilized as a surfactant or wetting agent in various industrial processes.

Application

Heptadecafluorooctanesulfonic acid potassium salt can be used as:
  • A fluorinated surfactant for poly(vinylpyrrolidone)/aminopropyl-functionalized nanoclay films to achieve hydrophobicity and oleophobicity.
  • A surfactant in the preparation of core-shell polymers for lithium-ion batteries.
  • A reactant to synthesize dicationic ionic liquids.
