الملخصHerein, we report the preparation and characterizations of polyvinyl alcohol (PVA) and polystyrene sulfonic acid (PSSA) blend nanocomposites reinforced with carbon black nanoparticles (CBNPs). The structural changes, interaction between CBNPs and the PVA/PSSA blend matrix were identified by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) studies. The surface morphology of PVA/PSSA/CBNP nanocomposite films were evaluated using polarized optical microscopy (POM) and scanning electron microscopy (SEM) and the mechanical properties were evaluated using bench top tester. In addition, the dielectric properties of PVA/PSSA/CBNP nanocomposite films with different loadings of CBNPs were carried out in the frequency range 50 Hz to 20 MHz at various temperatures ranging from 40 to 150 °C. The dielectric constant as high as 1851 (50 Hz, 150 °C) was obtained for the PVA/PSSA/CBNP nanocomposite film with 5 wt% CBNPs loading and for the same compositions the dielectric loss was about 3.9 (50 Hz, 150 °C. The dielectric results demonstrate that the dispersion of CBNPs has a significant control on the percolation threshold of nanocomposites. The enhanced dielectric performance of these nanocomposites infers that CBNPs are ideal nanofillers for the development of novel high-k materials with low percolation threshold for flexible energy storage applications.
