Solubilization of styrene in the catanionic system dodecyltrimethylammonium hydroxide- n ′-dodecanephosphonic acid

Formation of Well-Defined Vesicles by Styrene Addition to a Nonionic Surfactant and Their Polymerization Leading to Viscous Hybrid Systems

“…A two-state model on solubilization of styrene into the micelles was described before suggesting that while some styrene monomers are solubilizing into the micellar corona, others absorbed at the surface because of the surface activity of aromatic units at the water–hydrocarbon interface. , Both so-called “dissolved state” and “adsorb state” in general depend on the solubilizate type and amount . Another study of styrene solubilization in the catanionic surfactant demonstrated the styrene to be adsorbed at the micelle surface, whereas the vinyl group was located closer to the hydrocarbon core than the aromatic ring …”

“…Previous studies showed that size and morphology can be controlled during the polymerization of surfactants containing a polymerizable counterion . Detailed work was done by Walker et al where a rod-like system was used as the template and by systematically varying the reaction conditions, the dimension of the final aggregates could be controlled. , A frequently employed monomer is styrene because of the ease of its polymerization and the fact that its solubilization into micellar solutions has been studied before. , Soltero et al. examined the polymerization of styrene in wormlike micelles of the cationic cetyltrimethylammonium tosylate surfactant concluding that wormlike structures were fixated by polymerization.…”

“…22,23 A frequently employed monomer is styrene because of the ease of its polymerization and the fact that its solubilization into micellar solutions has been studied before. 24,25 Soltero et al examined the polymerization of styrene in wormlike micelles of the cationic cetyltrimethylammonium tosylate surfactant concluding that wormlike structures were fixated by polymerization. However, depending on the concentration, the formation of spheroidal polymer particles also took place in parallel.…”

“…30 Another study of styrene solubilization in the catanionic surfactant demonstrated the styrene to be adsorbed at the micelle surface, whereas the vinyl group was located closer to the hydrocarbon core than the aromatic ring. 24 In the present work, short rod-like micelles consisting of nonionic TDMAO and a small amount of Pluronic L35 (EO 11 PO 16 EO 11 ) were employed, where L35 was included to stabilize sterically the formed self-assembled systems (as seen in previous experiments 31 ). To this system, the styrene monomer was added to allow for templating via polymerization.…”

Are the mixtures of homologous surfactants ideal?

“…The main work in this sense was devoted to electrostatic interactions, while scarce attention has been put on the steric ones, mainly on the hydrophobic group geometry. Some work was devoted to the nature of molecular interactions in mixed micelles [1][2][3][4][5][6][7].…”
