Polymeric nanocomposites were prepared by inserting graphene and/or Ag, Au and ZnO nanoparticles in a TEGDA (tetraethyleneglycol diacrylate) polymer matrix. The polymeric films were characterized in terms of their dielectric properties by electrochemical impedance spectroscopy. The impedance data were fitted by generalized relaxation functions in order to determine conductivity, dielectric response and molecular relaxation time of the nanocomposite films. In particular, a stretched exponential function, Kohlrausch-Williams-Watts KWW), was used to investigate polymer/graphene/metal nanocomposites.
