Phase behavior and self-assembly aggregation of hydrocarbon and fluorocarbon surfactant mixtures in aqueous solution

Probing the Self-Assembly of Unilamellar Vesicles Using Time-Resolved SAXS

“…These two conditions can be met with a mixture of hydrocarbon and fluorocarbon surfactant system of oppositely charged head groups. The lower compatibility of fluorocarbon and hydrocarbon chains makes the hydrophobic part bulkier while the head groups strongly attract each other [7]. As a result, vesicle phase can be observed over a wide concentration range of the two components [8].…”

“…The experiments presented in this chapter are performed using dilute solutions of anionic lithium perfluorooctanoate (LPFO) and zwitterionic tetradecyldimethylamine oxide (TDMAO) surfactants, which form unilamellar vesicles over a broad concentration range [7,8]. Similar unilamellar vesicles can also be formed in the equivalent anionic and cationic surfactant mixtures, but due to the stronger head group interaction the formation process occurs more rapidly [16].…”

A class of efficient short-chain fluorinated catanionic surfactants

“…Thus, the problems related to the formation of solid crystalline phases and high Krafft points often found in the fluorinated surfactants, 32 do not play a role in this family of surfactants.

“…25 In the recent literature, hybrid double-chain surfactants having either two semi-fluorinated chains, 21 or one hydrocarbon and one partially-or fully-fluorinated chain, have also been reported. 32 The examples of salt-free catanionic mixtures, which are considered 'true' catanionic surfactants, are rare in the literature. Unfortunately, a disadvantage of these structures is that their Krafft points are usually higher compared to single chain amphiphiles which often makes them water insoluble at room temperature.…”

Interaction between a hydrophobic rigid face and a flexible alkyl tail: Thermodynamics of self-assembling of sodium cholate and SDS

“…The research on the molecular selfassembling of mixed surfactant solution has made an impressive progress in recent years [1][2][3][4][5][6][7][8]. These binary systems were shown to provide better performances than the individual surfactant systems in many applications -drug delivery vectors, membrane mimetic systems, and water and soil treatments.…”
