Abstract

The temperature and scan-velocity dependence of more complex bundle formation in a thin polystyrene melt regime is examined. It is shown that both temperature and scan frequency affect the patterns created by the movement of a nanoscopic tip in contact with a polymer surface. The time-temperature dependence of the patterns are well-described by the WLF equation which typically used to described viscoelastic behavior. Analysis of the data further suggests that the Tg of the polymer is elevated in the region confined between the tip and the substrate.
