Phase Behavior of Homologous Perfluoropolyether Surfactants: NMR, SAXS, and Optical Microscopy

Mele, Stefania; Ninham, Barry; Monduzzi, Maura

Description

Self-assembled structures formed by perfluoropolyether (PFPE) carboxylates with Hydrophobic chain terminated by Cl-C3F6O, and either sodium or ammonium counterions, have been explored in aqueous binary systems. The focus is on the different counterion-specific micelles and liquid crystals formed. These have been detected and characterized via optical microscopy, SAXS, and NMR. All Cl-PFPE surfactants form lamellar and cubic liquid crystals independently of chain length and counterion....[Show more]
