Sedimentation-diffusion dynamics in colloid-polymer mixtures

Journal article

We show experimentally how a phase separated colloid-polymer mixture finds its sedimentation-diffusion equilibrium after initial fluid-fluid demixing. During this equilibration process we measure key parameters of the colloidal interface by assuming local mechanical equilibrium and we inspect the behaviour of the meniscus close to a vertical wall. It turns out that the kinetic pathway associated with the sedimentation process not only strongly depends on the overall colloid and polymer concen...
