fluorocarbon-hydrocarbon hybrid cationic surfactants

therefore, in the present work, two novel hybrid cationic surfactants (f4h6 and f6h6) were designed and synthesized using perfluorobutylsulfonyl or perfluorohexylsulfonyl and hexyl as the hybrid chains, connected via a cationic bridge of n-benzyl-n′,n′-dimethyl ethylenediamine (scheme 1), where the phenyl group and nitrogen atoms were expected to enhance not only the adsorption ability on

aggregation behavior of cationic fluorosurfactants in water,the effects on aggregate structure of factors such as surfactant and salt concentration, counterion type, and alkyl chain length were investigated. similar to hydrocarbon surfactants the fluorocarbon surfactants self-assemble into various aggregates such as micelles, threadlike micelles, vesicles, and other lamellar aggregates.

strong synergistic effect of cationic hydrocarbon surfactant

abstract mixing hydrocarbon surfactants with fluorocarbon surfactants is still an important strategy to improve the economic benefits and performances of fluorocarbon surfactants and expand their range of application. herein, we prepared a novel kind of hydrocarbon-fluorocarbon surfactant mixtures via mixing a cationic surfactant, cetyltrimethylammonium bromide (ctab), with a tri-block

cationic surfactants: self-assembly, structure-activity,2. structural diversity of biocompatible and ecologically friendly cationic surfactants . one of the promising approaches in the design of building blocks for biomedical applications, which include formulations for drug delivery, is the creation of new multifunctional environmentally friendly, cleavable, green, and less toxic cationic surfactant systems answering the biotechnological criteria

fluorocarbon-hydrocarbon hybrid cationic surfactants

in this work, starting from the viewpoint of synergistic role of molecular constitutional parts, two fluorocarbon-hydrocarbon hybrid cationic surfactants (f4h6 and f6h6) were designed, using perfluorobutylsulfonyl or perfluorohexylsulphonyl and hexyl as the hydrophobic tails, connected. credit authorship contribution statement
