Dynamics at the polymer/nanoparticle interface in poly (2-vinylpyridine)/silica nanocomposites
The static and dynamic properties of poly (2-vinylpyridine)/silica nanocomposites are
investigated by temperature modulated differential scanning calorimetry, broadband
dielectric spectroscopy (BDS), small-angle X-ray scattering (SAXS), and transmission
electron microscopy. Both BDS and SAXS detect the existence of an interfacial polymer
layer on the surface of nanoparticles. The results show that whereas the calorimetric glass
transition temperature varies only weakly with nanoparticle loading, the segmental mobility …
