The morphological, structural, and insulating impacts of adding NiO nanoparticles to PVA-PVP-SiC-based polymer composites are investigated in this work. PVA/PVP/SiC/NiO composites at various concentrations (0.0, 0.3, 0.7, and 1 percent by weight) were made via casting. Additionally, the addition of nanobubbles using an ultrasonic device demonstrated that these compounds have special qualities in comparison to other nanocomposites and greatly improved insulation because the nanoparticles increased the number of charge carriers in the polymer system and enhanced polarization. When the compound level reached 1% by weight, the dielectric constants and electrical conductivity dramatically increased by 40% and 21%, respectively, due to the buildup of charges at the particle-polymer interfaces. Because NiO compounds are semiconducting, they have continuously improved. FE-SEM and optical microscopy (OM) techniques were used to analyze the compounds’ structural characteristics. Additionally, the insulating qualities were investigated between 100 Hz and 5 MHz. These findings suggest that NiO compounds can be employed in a variety of nanodielectric materials and are more effective in enhancing electrical insulation.
