抄録

Novel methods for the characterization of polymer surface structure and surface molecular motion have been presented. Scanning viscoelasticity microscopy (SVM) was used in the studies of the surface mechanical properties of polymeric solids. Employing dynamic secondary ion mass spectroscopy (DSIMS) for the depth profiling of the chemical composition of end-labeled polystyrene (PS) film, the end group segregation at the air/solid PS interface was verified. It was revealed that the molecular motion at the surface of glassy polystyrene (PS) was fairly activated, compared with that of bulk one due to the surface segregation of chain end groups. These results indicate that surface glass transition temperature is depressed due to the increase in free volume near surface region. Temperature dependent X-ray photoelectron spectroscopy (TDXPS) was utilized for the characterization of surface molecular motion of symmetric diblock copolymers. The activation of molecular motion at the surface was also confirmed by TDXPS. The two-dimensional mapping of the surface mechanical properties for the polymer blend ultrathin films was carried out on a nanometer scale by using SVM. Composition profile along the thickness direction of polymer blend thin film was also evaluated on the basis of neutron reflectivity (NR).
