Abstract in different language: In this study, the effect of 0.75 weight percent filler silica (SiO 2 ) with PI or PA nanowires for dielectric properties of epoxy resin EPOXYLITE 3750 LV (ER) was studied. For this purpose, direct unidirectional conductivity measurements and broadband dielectric spectroscopy measurements were used to describe changes in the dielectric responses of ER/SiO 2 nanocomposites with nanowires in the frequency and temperature range. The presence of nanowires and nanoparticles in the epoxy resin affected the segmental dynamics of the polymer chain and altered the charge distribution in the system. These changes caused a change in permittivity values and a shift in local relaxation peaks in the imaginary permittivity and dissipation factor spectra of nanocomposites. Experiments have shown that temperature-dependent transitions of electrical properties in nanocomposites are associated with to relaxation processes.
