    Abstract

    The influence on relaxation dynamics of poly(vinyl acetate) of SiO x nanoparticles dispersed in the polymeric matrix was investigated by Local Dielectric Spectroscopy, measuring the phase loss angle in the polymer as a function of the distance from the nanoparticles. Both images of phase loss angle and acquisition of local dielectric spectra show two distinct features, namely, a faster relaxation dynamics when approaching the nanoparticle surface, and a rather large range of influence on polymer dynamics with respect to nanoparticle size, probe size, and gyration radius of the polymer.
