Synthesis and surfactivity of non-ionic fluorocarbon surfactant

Yongming Zhang

Open publisher page 2 citations

Abstract

A novel non-ionic fluorocarbon surfactant is prepared by the oligomerization of hexafluoropropylene oxide(HFPO) and 4-nonylphenol-ethoxylate(40).The structure and the surface properties of the surfactant are measured by FTIR and NMR.The results show that this non-ionic fluorocarbon surfactant can reduce the surface tension of water solution from 72.4 mN/m to 21.2 mN/m,with the cmc as low as 8.32×10-6 mol/L and the γcmc 26.5 mN/m.
