| Abstrakt v dalším jazyce: | Herein, flexible polyvinylidenefluoride (PVDF) nanocomposite films reinforced with different concentrations of graphene nanoplatelets (GNPs), montmorillonite (MMT) nanoclay and titanium dioxide ( TiO2) nanoparticles (NPs) were prepared using a simple and low-cost solution casting method. The surface morphology of PVDF/GNPs/TiO2/MMT nanocomposites and the interaction between PVDF, GNPs, TiO2 NPs and MMT nanofillers was examined using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) techniques. The dielectric properties of the prepared nanocomposite films were evaluated using a frequency response impedance analyzer in the frequency range from 50 Hz to 20 MHz at various temperatures. The electromagnetic interference (EMI) shielding effectiveness (SE) of PVDF/GNPs/TiO2/MMT nanocomposites was measured in the Ku-band region (12–18 GHz) and the maximum SE of 12.6 dB was obtained for nanocomposites with GNPs-2.5%, MMT-1% and TiO2- 11.5%. Considering the excellent EMI shielding performance, these nanocomposites can have promising applications in smart electronics and flexible devices. |
