Abstract
Both dielectric permittivity and dielectric loss factor have been measured for epoxy nanocomposites filled with multilayered graphene nanoplatelets within the frequency-temperature range of [4 Hz, 8 MHz] and [95, 350K]. The dielectric strength, dipole-dipole coupling energy, macroscopic, and molecular relaxation times have been calculated as functions of volume concentration of the filler. Physical reasons underlying variations in the parameters with increasing concentration have been discussed.
