“…The interactions of ionic surfactants with oppositely charged polyelectrolytes that are hydrophobically modified lead to a high degree of binding and mixed aggregates often formed between the surfactant and side chains at concentrations well below the critical micellar concentration. 23 Different stages were observed in the studied system (Fig. 5).…”

: Synthesis and association properties in water solution of random copolymers of 2-acrylamido-2-methyl-1-propane sulfonic acid and isodecyl methacrylate-potential application as surfactants in micellar-enhanced ultrafiltration processes. Fluorescence spectroscopy was used to further confirm the copolymers self-aggregate in water. Critical concentration of the self-aggregate formation (CAC) decreased by increasing the molar fraction of iDMA in the AMPS co copolymers and varied between 1.20 and 0.04 g/L depending on the degree of hydrophobic modification. Hence, copolymer composition and charge density allowed tuning the pseudomicellar characteristics of these new amphiphilic copolymers. The addition of a salt or a low-molecular-weight surfactant was studied. Binding of CTAB to the AMPS co copolymers leads to a high decrease of CAC, i.e., 0.006 g/L. Effect of the composition in the viscosimetric behavior of the hydrophobically modified copolymers AMPS co was investigated. The removal of single metal ions, Cu 21 , and m-cresol from aqueous solutions by ultrafiltration with the help of the copolymers was investigated. Equilibrium dialysis experiments demonstrate that the formation of hydrophobic microdomains can be used to control the sequestration of foulants, and thus these novel copolymers have potential application as polymeric surfactants in micellar-enhanced ultrafiltration processes for water purification.

“…is caused by the grafting of lipophilic modifications. Hydrophobically modified polymers in concentrations on the order of 1% have been reported to form hydrophobic microdomains that can solubilize hydrophobic molecules, see, for example, the review by Piculell et al (26). The concentration of these domains can be calculated by dividing the concentration of alkyl groups by the aggregation number of lipophilic modifications in one domain.…”

“…Mixtures of polymers and surfactants of opposite charges have been the subjects of many theoretical studies, both in bulk and at interfaces: see for example reviews and books covering these different aspects [1][2][3][4][5][6]. Polyelectrolyte and surfactant of opposite charge can form hydrophobic complexes in bulk [7,8] at a surfactant concentration called the Critical Aggregation Concentration (CAC) that is often much smaller than the Critical Micelle Concentration (CMC), due to the strong electrostatic interaction between the polyelectrolyte charged groups and the ionic polar heads of the surfactant.…”

Résumé -Amélioration de la stabilité d'émulsions ou de mousses aqueuses à l'aide de systèmes mixtes tensio-actif/polymère de charges opposées -Les propriétés émulsifiantes et moussantes de systèmes mixtes tensio-actif/polymère ont été étudiées. L'addition d'une faible concentration d'un polyélectrolyte de charge opposée au tensio-actif permet d'améliorer la stabilité d'une émulsion ou d'une mousse aqueuse, à des concentrations en tensio-actif très faibles, typiquement inférieures à la CMC, ce qui correspond à des gammes de concentrations où le tensio-actif seul ne permet pas de stabiliser le système dispersé macroscopique. Cet effet s'explique par la co-adsorption de chaînes de polymères et de molécules de tensio-actifs à l'interface fluide/fluide et la formation d'un complexe polymère/tensio-actif possédant une forte activité interfaciale. La complexation entre les 2 espèces et, par conséquent, la stabilité de l'émulsion ou de la mousse peuvent être contrôlées en ajustant les interactions électrostatiques entre les deux espèces chargées. Des polymères amphotères peuvent être utilisés pour obtenir des systèmes ajustables, en permettant le contrôle de la stabilité d'émulsions ou de mousses par le pH.
