  • (PDF) Influence of Polymer Charge Type and Density

    The adsorption of modified polyacrylamides (PAM) at the silica surface has been studied by ellipsometry. To study the influence of the type of modification of the polyacrylamide on the adsorption behaviour, we have used cationic, anionic and hydrophobically modified polyacrylamides with varying charge density and degree of hydrophobisation. The adsorbed amount and adsorbed layer thickness were ...
