Abstract

Solvent isotope effects on the micellization behavior of fluorosurfactants have been investigated. The critical micelle concentration and the micelle ionization degree for 2-hydroxy-1,1,2,3,3-pentahydropefluoroundecyldiethylammonium halides in D₂O were lower than those in H₂O. The stronger hydrogen bonding in D₂O enhanced the micelle growth accompanying counterion binding.
