Floating nanobuoys (Molecular Dynamics simulations of a nanoparticle floating on polymeric liquid film) — •Juan G. Diaz O., Martin Aichele, Wolfgang Paul, and Kurt Binder — Institute for Physics, Johannes Gutenberg University, Staudinger Weg 7, D-55099 Mainz, Germany

In this investigation we want to understand the dynamics of nanoparticles (in the order of 5nm) on thin polymeric films, using Molecular Dynamics techniques. We consider in our simulations a bead-spring model of a polymer film adsorbed on a non-structured atractive wall. The particle is modelled as a Lennard-Jones one and we study its equilibrium height in the film as well as its dynamics at the film surface. The response of the polymer to the presence of the nanoparticle also is investigated.
