Influence of the polymer backbone rigidity on polyelectrolyte–surfactant complexes at the air/water interface

Interaction of cationic surfactants with carboxymethylcellulose in aqueous media

“…The onset of CAC and various stages of interaction after CAC were very clearly detected. Langevin and co-workers have examined in detail the influence of polymer charge density [10], polymer molecular weight [11], polymer backbone rigidity [12], and surfactant alkyl chain length on the complexation of C n TAB with anionic polyelectrolytes [13]. They have shown that complexation is shifted to low surfactant concentration with increasing alkyl chain length.…”

Interaction between poly(vinylimidazole) and sodium dodecyl sulfate: Binding and adsorption properties at the silica/water interface

“…The rectangular (20 × 10 mm) open frame, made from a 0.19-mm-diameter platinum wire, was attached to a force transducer (HBM Q11) mounted on a motor, allowing it to be drawn away from the surface at a controlled constant rate. For mixed solution at low concentrations of surfactants, the approach to the equilibrium could take more than 3 h [39], and we did not find any reliable method to obtain the equilibrium surface tension of such a system by extrapolation to infinite time. Thus, it was assumed arbitrarily that equilibrium had been reached when the surface tension variation was less than 0.01 mN m −1 over 10 min.…”

Tuning Molecular Recognition in Water‐Soluble Nanogels with Enzyme‐Like Activity for the Kemp Elimination

“…These molecules are often used in combination with natural or synthetic polymeric materials and their interactions in aqueous media have been studied to understand the nature of their characteristics and derive structure-activity relationships. [16] Polymersurfactant associations can be influenced by physical and chemical factors related to the ionic character, the nonpolar tail of the surfactant, [22] polymer hydrophobicity, [23] and the structural conformation and flexibility of the polymer chain. [24] Although a number of studies have evaluated linear poly(acrylic acid) polymer-surfactant systems, [25][26] less research has been carried out on cross-linked networks.…”
