Enhanced electromagnetic interference shielding effectiveness in multiphase nanocomposites based on poly(vinylidene fluoride-co-hexafluoropropylene), nano-Fe2O3, graphene nanoplatelets, and nanodiamonds
Original language description
Iron oxide (Fe2O3) nanoparticles (NPs), graphene nanoplatelets (GNPs), and nanodiamonds (NDs) reinforced poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) nanocomposites were synthesized by a solvent casting technique. The structure and morphology of synthesized nanocomposites were studied using Fourier-transform infrared spectroscopy, X-ray diffraction, and scanning electron microscopy. The thermal behavior of polymer nanocomposites (PNCs) was studied by the thermogravimetric analysis and the derivative thermogravimetry. The dielectric measurements were carried out within the temperature range from 40 to 150C and in the frequency range from 50 Hz to 15 MHz. At 50 Hz, 140C, the highest dielectric constant of 92.46 was noted, for the PVDF-HFP + 10 wt% Fe2O3 + 6 wt% GNPs + 3 wt% NDs and the highest dielectric loss tangent has been observed to be 24.75 at 50 Hz, 140C for the PVDF-HFP + 10 wt% Fe2O3 + 4 wt% GNPs + 2 wt% NDs. The electromagnetic interference shielding effectiveness (EMI SE) was studied in the X-band and Ku-band frequency regions (8–18 GHz). High EMI SE values of 31.60 dB and 34 dB were observed for PVDF-HFP/Fe2O3/GNPs/NDs nanocomposites with 10 wt% Fe2O3 + 8 wt% GNPs + 4 wt% NDs in X-band and Ku-band, respectively. These findings suggests PVDF-HFP/Fe2O3/GNPs/NDs-based PNCs as an appealing material for EMI shielding applications.
