The interactions between the mixed surfactants sodium dodecyl benzenesulfonate (SDBS) and modified oil ethoxylate (SOE‐60) with polyvinylpyrrolidone (PVP) were studied at 25 ± 1 °C using a surface tension meter, Ubbelohde viscometer, and fluorescence spectrophotometer. Interaction mechanisms of SDBS/SOE‐60‐PVP systems were explained by the “necklace and bead” model. The results showed that the interaction could be divided into three parts by two characteristic concentrations: the critical aggregation concentration (cac) and the polymer saturation point (psp). The interaction mechanisms of SDBS/SOE‐60‐PVP systems are consistent with the “necklace and bead” model. The binding mixing surfactant micelles, formed by free SDBS and SOE‐60 molecules, were bound to PVP chains by hydrophobic and ion–dipole interactions. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

“…Of increasing interest are methods allowing creation of non-lipid vesicles in order to enhance liposomal stability [1,15]. Combinations of surfactant mixtures [16][17][18][19][20] have been used to initiate assembly and increase the thermodynamic stability of vesicles under different environmental conditions, including aging time, temperature, pH, and pressure [20][21][22][23].…”

“…The surface tension of the SDBS-CTAB mixture solution was only partly lower than that of CTAB and the lowest one of the mixture was at the mole ratio of 1:1. A similar experiment was also carried out by Zhai et al [39], and it was reported that the desirable mole ratio of SDBS/CTAB should be 1:1. In this study, the lowest surface tension of the SDBS-CTAB mixture, about 38.2 mN/m, also appeared at the mole ratio of 1:1, which was mainly due to the strong interaction between the anion and cation and their synergy [40,41].…”

Black carbon (BC) particles were removed from experimental flue gas by the surfactant solutions of sodium dodecylbenzene sulfonate (SDBS), hexadecyl trimethyl ammonium bromide (CTAB), fatty alcohol polyoxyethylene ether-9 (AEO-9) and polyoxy ethrlene nonyl phinyl ether-10 (TX-10), as well as AEO-9-SDBS, AEO-9-CTAB and SDBS-CTAB, in a new type of umbrella plate scrubber. Among the four independent surfactants, AEO-9 has the lowest surface tension, 35.9 mN/m, which resulted in the highest BC removal ratio among the alone surfactants. The experimental conditions were as follows: dust concentration = 3000 mg/m3; gas velocity = 14 m/s; liquid-gas ratio = 0.80 l/m3; and gas flow = 400 m3/h. When the mole ratio of the mixed surfactants was 1:1, the lowest surface tension could be detected among the studied mixed surfactants. According to the molecular interaction parameters (beta) and the mole ratio of surfactant 1 in the mixture (x1), the synergistic effects of AEO-9-SDBS and SDBS-CTAB solutions were obviously higher than those of AEO-9-TX-10 and AEO-9-CTAB. Therefore, AEO-9-SDBS solution had the lowest surface tension among the mixtures due to its beta < 0 and x1 = 0.85. The mixture solution of AEO-9-SDBS (1:1 mole ratio, 0.2 mmol/l) yielded the highest BC removal ratio, about 99.8%, and it was about 12% higher than that of only water, which was about 87.9%. The calculated critical micelle concentration was almost the same as that of the experimental concentration when the related equation was corrected by beta.
