Studies of the Interaction of Cationic Gemini Surfactants with Polymers and Triblock Copolymers in Aqueous Solution

Interactions of quaternary ammonium salt-type gemini surfactants with sodium poly(styrene sulfonate)

“…The interaction between the cationic surfactant alkyltrimethylammonium bromide or chloride and anionic polymer such as polyacrylamide sulfonate, polystyrene sulfonate (PSS), DNA and xanthan has been investigated [6][7][8][9][10][11][12][13]. Although many studies of the properties of the conventional monomeric surfactant/uncharged polymer mixed systems have been reported, there have been few reports about those of gemini surfactant/polymer mixed systems [14,15]. Gemini surfactants, which have two hydrocarbon chains and two hydrophilic groups in a molecule, reportedly possess unique properties, such as better solubilization, lower Krafft temperatures, lower critical micelle concentration (cmc), greater efficiency in lowering the surface tension, and foaming properties than the conventional monomeric surfactants [16][17][18][19].…”

Determination of critical micelle concentration of sodium dodecyl sulfate in butyl acrylate emulsions

“…Research have been carried for emulsifier stability using SDS as an anionic surfactant and CMC of SDS but lacked on particle size and solid content [17,18].…”

Study on the viscosity of cationic gemini surfactant–nonionic polymer complex in water

“…The polymer-surfactant complex should display special viscosity behavior in aqueous solution if the molecular interaction of polymer and surfactant occurs. To our knowledge, there are few reports on the interaction between gemini surfactants and nonionic polymers [16,17]. Moreover, in most of the available literature on nonionic polymer-surfactant systems, the viscosity behavior of these systems in aqueous solution was considered to be dependent only on the concentrations of surfactant and polymer, but ionization of the surfactant micelles in polymer-surfactant aqueous solution was ignored [3][4][5]8].…”
