Abstract
A molecular dynamics simulation was used to investigate the adsorption of single-chain polystyrene on the graphite surface. The results show that the structures of the adsorbed PS are usually elongated in shape rather than circular from the top view; there is an exponent relationship between the component of the mean square radius of gyration parallel to the surface and the number of monomers, and the exponent obtained is about 1.04; the main driving force is the van der Waals force between chain segment and surface.
