中文摘要：
采用分子动力学（MD）模拟方法研究了单链聚苯乙烯（PS）在石墨表面的吸附．模拟结果表明，吸附后PS在平行于石墨表面的方向可视为准二维椭圆结构，并且在此方向上的均方回转半径值（R^2∥）与其所含单体数目（N）具有指数关系R^2∥～N^2v，指数2v约等于1．04；最后指出PS吸附过程的主要驱动力为PS链段与表面之间的范德华作用力．
英文摘要：
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.
