Abstract

Surface dynamics in monodisperse polystyrene films was examined by lateral force microscopy in conjunction with dynamic secondary ion mass spectroscopy. Glass transition temperature, T_g, at the surface was markedly lower than the corresponding bulk T_g. Also, it was shown that polymer chains present at the surface could diffuse even at a temperature below the bulk T_g. The surface depth, in which molecular motion was activated, was of the order of 5 nm.
