    Activated physical properties at air-polymer interface

    The surface molecular motion of monodisperse polystyrene (PS) films was examined using scanning viscoelasticity microscopy (SVM) in conjunction with lateral force microscopy (LFM). The dynamic storage modulus,E′,...

    Grazing Incidence X-ray Diffraction Study on Surface Crystal Structure of Polyethylene Thin Films

    Crystal structure in thin films of melt-crystallized and annealed polyethylene (PE) was examined by grazing incidence X-ray diffraction measurements. Choosing appropriate incident angles of X-rays to the films...

    Relationships between lateral force and viscoelastic properties for amorphous polymer films based on lateral force microscopy

    The relationships between lateral force and viscoelastic properties of amorphous polymer surfaces with Tg’s lower and higher than room temperature (295 K, RT) and their blend systems have been studied on the b...
