Monte Carlo study of polymer adsoprtion on nanocylinders — Jonathan Gross1 and •Michael Bachmann2 — 1Universität Leipzig, Leipzig, Germany — 2The University of Georgia, Athens, GA, USA
The thermodynamic behavior of a coarse-grained flexible polymer model in the vicinity of an attractive nanocylinder is subject of this investigation. We are interested in the structural phases of the polymer and how they change with the surface attraction strength of the nanocylinder. The effective monomer-surface attraction strength is associated with the cylinder radius and its material. Previous studies of polymer adsorption on planar surfaces already provide insight in the structures formed by adsorbed polymer chains. Recently also the adsorption on curved surfaces was investigated. We try to connect the results of the adsorption on curved and planar surfaces, since in the limit of an infinite radius of the cylinder, the surface has the same characteristics as a plane. We construct complete pseudo-phase diagrams of a 30-mer interacting with nanocylinders of five different materials as a function of temperature and radius of the cylinders.
