Phase behavior, rheological property, and transmutation of vesicles in fluorocarbon and hydrocarbon surfactant mixtures.
We present a detailed study of a salt-free cationic/anionic (catanionic) surfactant system where a strongly alkaline cationic surfactant (tetradecyltrimethylammonium hydroxide, TTAOH) was mixed with a single-chain fluorocarbon acid (nonadecafluorodecanoic acid, NFDA) and a hyperbranched hydrocarbon acid [di-(2-ethylhexyl)phosphoric acid, DEHPA] in water. Typically the concentration of TTAOH is ...
متن کاملThe New Fluorocarbon- Hydrocarbon Unsymmetrical Bolaform Surfactant: A Novel Anti-Foaming Agent
We report the interfacial properties of a new fluorocarbon-hydrocarbon hybrid surfactant [OH(CH2)11N(C2H4)2(CH2)2(CF2)5CF3 I, or FHUB], which has a fluorocarbon chain as well as a w-hydroxyalkyl chain. This new hybrid surfactant has properties that are different than classical hydrocarbonand fluorocarboncontaining surfactants. This difference is created by combining a fluorocarbon chain and the...
متن کاملExplicit- and implicit-solvent simulations of micellization in surfactant solutions.
In this article, we focus on simulation methodologies to obtain the critical micelle concentration (cmc) and equilibrium distribution of aggregate sizes in dilute surfactant solutions. Even though it is now relatively easy to obtain micellar aggregates in simulations starting from a fully dispersed state, several major challenges remain. In particular, the characteristic times of micelle reorga...
متن کاملSynthesis and pH-dependent micellization of diblock copolymer mixtures.
This work focused on the preparation and the aqueous solution properties of hybrid polymeric micelles consisting of a hydrophobic poly(epsilon-caprolactone) (PCL) core and a mixed shell of hydrophilic poly(ethylene oxide) (PEO) and pH-sensitive poly(2-vinylpyridine) (P2VP). The hybrid micelles were successfully prepared by the rapid addition of acidic water to a binary solution of PCL(34)-b-PEO...
متن کاملCompetition between surfactant micellization and complexation by cyclodextrin.
Supramolecular property systems composed of alkyltrimethylammonium surfactants and β-cyclodextrin were studied by means of a chemical probe. Solvolysis of 4-methoxybenzenesulfonyl chloride (MBSC) was used in the mixed systems with the aim of being able to determine the concentration of uncomplexed cyclodextrin in equilibrium with the micellar system. The surfactants used enabled us to vary the ...
