Abstract

We show, and support with experiments, two limiting regimes of polymer adsorption-desorption. When these processes are rate limited by diffusion they are expected to be non-exponential in time and the time constant is inversely proportional to the diffusion coefficient. When these processes are rate limited by the energetics of surface detachment, they are expected to be exponential in time and the time constant is exponential in the molecular weight. This suggests a unifying perspective from which to analyze polymer mobility at surfaces.
