The interactions of neutral polymers with surfactants have a key role in detergency and are systems of current academic and commercial interest. Here, we propose to study the competitive adsorption, complexation and displacement of a neutral polymer (PVP) with an anionic surfactant (SDS) and anionic particles (colloidal silica). The effect of polymer coverage will be investigated with experiments being performed at different positions along the adsorption isotherm to look at the interactions between surfactant and the surface complex as the proportions of loops, trains and tails changes with surface coverage.
