Aqueous dispersions of hydrophobic high-molar-mass cellulose-graft-polystyrene (Cel-g-PS) copolymers were prepared by nanoprecipitation from dioxane solutions using sodium dodecyl sulfate as a stabilizer. The size and structure of formed Cel-g-PS nanoparticles were studied by scattering techniques (static and dynamic light scattering, SAXS) and transmission electron microscopy. The scattering and microscopy data show that nanoprecipitation of Cel-g-PS leads to the formation of polydisperse aggregates of collapsed Cel-g-PS macromolecules containing entrapped SDS micelles in the kinetically frozen state.The final size of the aggregates can be tuned by changing the copolymer concentration, c P , in the dioxane solution. The average hydrodynamic radius of the aggregates, R H , scales as-1] ~ c P , where R H,0 is the R H value extrapolated to the zero copolymer concentration.

Two kinds of Pluronics (PEO-PPO-PEO triblock copolymers) were used in these studies. They have mixed with anionic surfactant (sodium oleate). The adsorption isotherms of surfactant and copolymer-surfactant mixture onto dolomite have been determined. The adsorbed amount of the Pluronics increases with increasing concentration and reaches plateau. An increase of adsorbed amounts of anionic surfactant onto the mineral surfaces (dolomite) has been observed at the presence of Pluronic copolymers. The adsorption effect of triblock copolymers has been investigated on the zeta potential of dolomite at the water suspension. The interaction of anionic surfactant with copolymers causes a decrease of zeta potential to small amount due to the deformation of double electrical layer. The adsorbed non-ionic Pluronic layer partially screens the surface charge of mineral particles, and thus, reduces the zeta potential. On the other hand, the adsorption of anionic surfactant and copolymer caused a decrease of negative value of zeta potential both investigated minerals. The stability of dolomite suspension depends on the both copolymer and sodium oleate concentrations.

“…When mixing the two compounds, highly surfaceactive complexes can form due to electrostatic interactions. 4,5 Polyelectrolyte/surfactant mixtures play an important role in cleaning products and cosmetics. 6,7 Depending on the charge combination of the used polyelectrolytes and surfactants, either a Common Black Film (CBF) with a thickness of 10-100 nm, or a Newton Black Film (NBF) with a thickness below 10 nm is formed as the final state before film rupture.…”

a Polyelectrolyte/surfactant mixtures of rigid monosulfonated poly(phenylene sulfone) (sPSO 2 -220) and tetradecyl trimethylammonium bromide (C 14 TAB) were investigated by surface tension, surface elasticity and foam film stability measurements. The results were compared to former measurements of polyelectrolyte/ surfactant mixtures containing more flexible polyelectrolytes (PAMPS or PSS and C 14 TAB). For all polyelectrolyte/ surfactant mixtures an increased surface adsorption in comparison to the pure surfactant was detected.Moreover, sPSO 2 -220/C 14 TAB mixtures showed a much higher surface activity and foam film stability than mixtures with more flexible polyelectrolytes. The results presented give insight into the surface adsorption and foam film formation of rigid polyelectrolyte/surfactant mixtures. Therefore, this study helps to understand the role of polyelectrolyte backbone rigidity in the formation and stabilization of foam films made from polyelectrolyte/surfactant mixtures.
