“…Rayleigh light scattering is an effective and powerful tool for researching aggregation behavior of surfactant and surfactantpolymer systems because of its rapidity, simplicity, and sensitivity. 31 RLS measurements of the SDBS/SOE-60-PVP system are presented in Figure F6 6. It can be observed that the three curves all have two break points: cac and psp.…”

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.

“…Besides the two preceding studies of synthetic PEL solutions, recently dynamic surface tension (DST) measurements have been used to investigate polymer–surfactant interactions highlighting influences of the surfactant structure and the nature of the surfactant head group on the polymer–surfactant interactions and PEL‐surfactant complexes respectively – all using Wilhelmy plate technique, the latter one using in addition drop and bubble profile analysis tensiometry with data evaluation after .…”

Characterization of highly substituted, cationic amphiphilic starch derivatives: Dynamic surface tension and intrinsic viscosity

The surface activity and viscometric behavior of highly substituted, amphiphilic polysaccharides, derived from potato starch by modification with benzyl‐ and hydroxypropyl‐trimethylammonium groups, are studied in salt‐free and 0.05 M NaCl aqueous solution. For the first time dynamic surface tension measurements of amphiphilic starch derivatives have been effected using the pendant drop method and it was possible to correlate them with particle sizes and apparent charge density. Rheological investigation of large concentration ranges (0.01–20 g/L) is used to discuss Huggins plots and typical polyelectrolyte (PEL) behavior for all starch derivative samples could be found. The determination of overlap concentration and, in dilute aqueous solution, of intrinsic viscosity was possible. For the latter one the semi‐empirical equation of Rao was used, making it possible to get insights to PEL conformation in dependence on the degrees of substitution (DS) of both substituents. It is shown that for intrinsic viscosity an inversion of the impact of both substituents takes place, with hydrophobic benzyl groups on the one hand and cationic hydroxypropyl‐trimethylammonium groups on the other. Data evaluation via the ratio of both DS values had been successfully utilized and thus, the applied method has been identified as being a promising tool to compare a multitude of starch derivatives with substituents of different polarity in various DS to get tendencies regarding overall hydrophobicity.

“…Moreover, the surface tension was minimum, and the apparent viscosity was maximum when the concentration of Tween‐80 was the same; this showed evidence of the formation of high‐surface activity aggregates. When the concentrations were previously the CAC, there was the comicellar network formation of the polymer and surfactant micelles because of the cooperative hydrophobic interaction . The AM/AA/NAE/Tween‐80 system indicated that viscosity enhancements were yielded by the addition of Tween‐80.…”

A hydrophobically associating copolymer was prepared by free-radical polymerization with acrylamide (AM), acrylic acid (AA), and N-allyloctadec-9-enamide (NAE) as monomers. The structure was characterized by Fourier transform infrared spectroscopy, 1 H-NMR, 13 C-NMR, and scanning electron microscopy. The rheological experiments indicated that the copolymer possessed superior properties compared with partially hydrolyzed polyacryamide. It was found that an AM/AA/NAE/Tween-80 system could effectively decrease the interfacial tension and reduce the surfactant loss caused by stratum adsorption in polymer-surfactant flooding.
