Abstract

Photon correlation spectroscopy measurements have been performed on aqueous silica dispersions containing physisorbed poly(ethylene oxide) in the presence of the surfactant sodium dodecyl sulfate. From the measurements, it appeared that near complete desorption of the polymer occurred around the critical micelle concentration of the pure surfactant. However, at very high surfactant concentrations, the apparent hydrodynamic thickness returned to its initial value in the absence of surfactant. The results are discussed in terms of the specific interactions between the polymer and the surfactant.
