The simultaneous adsorption of three poly(ethylene oxide) (PEO) with different molecular weights and two cationic surfactants on silica under a constant feed concentration of PEO has been investigated in aqueous solutions. Two cationic surfactants were used; dodecyltrimethylammonium bromide (DTAB) a
The adsorption of a series of amphiphilic poly(ethylene oxide)poly(DL-lactide) (PEO-PL) diblock copolymers at the water/silica interface was investigated by ellipsometry and reflectometry. For all copolymers, a much higher saturation adsorption is found compared to that of the PEO homopolymers, indi
Adsorption of telechelic polymers (hydrophobically end-capped poly(ethylene oxide)) on charged colloidal particles modifies the characteristics of the electrical double layer. These interfaces were found to be able to protect colloids against aggregation or to induce colloid destabilization dependin
