摘要：

Perfluoropolyether carboxylates having sodium, potassium or ammonium counterions, and hydrophobic chains, mostly Cl-C3F6O- terminated, have been investigated in aqueous binary systems, with the focus laid upon the counterion effect on the major self-assembly features. Micellization and liquid crystal formation have been detected via surface tension, conductivity, optical microscopy and NMR. (C) 1999 Elsevier Science B.V. All rights reserved.
