“…Herein, we try to interpret our experimental results based on the pseudo phase equilibrium hypothesis, which was widely applied in the description of surfactant aggregation. 43,[61][62][63][64][65][66][67] The equilibrium between the surfactants adsorbed on the polymer IC chains and in the solution may be characterized by…”

The interactions between the anionic polymer ι-carrageenan (IC) and the cationic surfactants 1-dodecyl-3-methylimidazolium bromide (C12mimBr), dodecyltrimethylammonium bromide (DTAB) and ethyl-α,ω-bis(dodecyldimethylammonium)dibromide (12-2-12) have been studied by fluorimetry and isothermal titration calorimetry. Our experimental results showed that at a low surfactant concentration, the monomers adsorbed on the IC chains through the electrostatic attraction, followed by the formation of induced micelles on the IC chains through the hydrophobic interaction until the IC chains are saturated by surfactant molecules; after that the added surfactant formed free micelles in the solution. A pseudo-phase-equilibrium thermodynamic model was proposed to explain the experimental results and to understand the mechanisms of the interactions in these three systems. Moreover, the salt effect on the interactions was investigated and found that it changed the critical concentrations but not the interaction mechanism.

“…Owing to their unique molecular structure, gemini surfactants have exhibited a much superior performance compared with the corresponding conventional surfactants. They have lower critical micelle concentration (CMC) values, better wetting, foaming and lime-soap dispersing properties, can more effectively reduce the surface tension and so on [3][4][5].…”

The interaction between a novel anionic gemini surfactant containing a triazine ring, denoted as C8-G, and cetyltrimethylammonium bromide (CTAB) has been investigated in aqueous solution. The surface tension vs log. molar concentration plots of the individual surfactants and their mixtures were measured at different temperatures (298, 303, 308, and 313 K) by the drop volume method. The surface properties and the interaction parameters of the adsorption monolayer and the mixed micelle were obtained from the plot. The results showed that the CMC of the C8-G/CTAB mixture reached a minimum value of 3.20 9 10 -5 mol/L when a G (the mole fraction of C8-G in the mixed system) was 0.7 at 308 K, and the minimum c CMC was 28.1 mN/m obtained for the molar ratio of 0.9 at 308 K. Interaction between the two components was strongest ( b r j j ¼ 14:158; b m j j ¼ 11:851) when a G was 0.7 at 303 K. All the C8-G/CTAB mixtures exhibited synergism in both surface tension reduction efficiency and mixed micelle formation except when the mole fraction of C8-G (a G ) was 0.1, 0.5 and 0.9 at 313 K, and became greatest for the molar ratio of 0.7 at 303 K. The C8-G/ CTAB mixtures exhibited synergism in surface tension reduction effectiveness for all the complex ratios at 303 K, a G = 0.1, 0.3, 0.9 at 308 K and a G = 0.7 at 313 K, whereas the other surfactant mixtures did not show this synergism.

“…Numerous application properties of surfactants are based on two basic physical and chemical characteristics: micelle formation and surface adsorption (Ding et al 2013;Łudzik et al 2013). All of the tropisms of β M in Table 4 were negative, so the solution systems containing ML-AL and the tested anionic surfactant belonged to the negative deviation system (Liu and Mi 2003).…”

Surfactants made from modified lignin are attracting growing attention; therefore, a lignin-phenol nonionic surfactant named ML-AL has been prepared by modifying liquefied industrial alkali lignin (L-AL). Its basic physical and chemical properties have been shown to be favorable. In this work, anionic surfactants of sodium fatty acid soap (carbon numbers 12, 16, and 18) and sulfur-containing anionic surfactants (sodium dodecyl sulfate and sodium dodecyl benzene sulfonate) were chosen to mix with ML-AL in water-soluble media. The surface properties of each binary mixed solution system with anionic surfactant were investigated. At the same time, the mixed micelles formed by ML-AL and each anionic surfactant were studied. Non-ideal mixed micelles were obtained via ML-AL and the tested anionic surfactant. The interaction parameter (β M ) and excess free energy (ΔG excess ) were both negative. Meanwhile, the critical micelle concentration (CMC) values of mixed systems (formed by ML-AL and each anionic surfactant in aqueous solution) were lower than those of a single-component system (ML-AL or single anionic surfactant). There was an optimum dosage ratio of about 0.4 in terms of synergistic effects. This research could provide a foundation for practical applications of combinations with anionic surfactants in aqueous solution.
