The behavior of thin polymer films adsorbed on a graphite surface was investigated by means of atomic force microscopy. Via force-distance curves, which were recorded for layers of polyisoprene adsorbed on graphite [highly ordered pyrolytic graphite (HOPG)], a two-layer system was found. The upper layer proved to be soft and not in the glass state. No indications supporting the supposition of an additional glasslike polyisoprene layer underneath this soft layer could be found. Thus, if such a glass layer exists on the HOPG surface, the upper limit of its thickness is set to 3 nm. On the other hand, polystyrene adsorbed on graphite is in the glass state independent of thickness.
