Polyelectrolyte structuring of fine kaolin particles leads to enhanced optical performance in paper coating applications. In this investigation, the interaction between such a polymer and kaolin has been probed by applying traditional surface chemical concepts supplemented by computer modeling to simulate adsorption behavior. We measured polymer adsorption isotherms and monitored surface chemistry changes during polymer adsorption. In conjunction with the surface chemistry studies, a variety of molecular modeling techniques were used to investigate charge distribution, polymer flexibility and adsorption behavior. By combining these results, we have a more detailed picture of the surface interaction.
