Perfluoroalkyl bilayer membranes prepared from saturated amphiphiles with fluorocarbon chains
Steinkopff eBooks2007pp. 149–155
Abstract
Ammonium-type F-alkylated surfactants characterized by the presence of two tails RF/R′F or RF/R′F have been prepared, and the vesicular behavior of some double-chain surfactants has been studied in ultrasound-treated aqueous dispersions. Stable vesicular aggregates were found which showed unilamellar membrane structures. Their shapes, hydrodynamic radii and size distriubtion were determined by dynamic light scattering and electron microscopy. The phase transition temperatures of aqueous dispersions of double-chain surfactants were measured by differential scannig calorimetry.
