Effect of non-conducting nanoparticles on PVDF for improved insulating properties

Abstract

This study investigates the effect of incorporating non-conducting calcium carbonate (CaCO₃) nanoparticles into polyvinylidene fluoride (PVDF) to improve its insulating properties. PVDF is widely used as an electrical insulation polymer because of its dielectric performance, thermal stability, and mechanical strength; however, these properties can be further improved for advanced applications through nanoparticle modification. PVDF--CaCO₃ nanocomposite samples were prepared, characterized, and tested for dielectric and mechanical properties. The results show that adding CaCO₃ nanoparticles improves the insulating response of PVDF, especially at 0.5 wt% and 1.0 wt%, making the nanocomposites promising materials for high-performance insulation in electrical and electronic devices. The findings demonstrate the potential of nanoparticle-modified PVDF for improving energy efficiency and reliability in insulation systems.
