In this research, the thermal and electrical characteristics of a polymer matrix composite with polyvinyl alcohol as a constituent (PVA) integrated with nanoscale silver particles (Ag NPs) were studied. The PVA-Ag NPs composite samples were meticulously fabricated through the casting process, incorporating varying weight percentages of nanosilver 0 %, 1 %, 3 %, and 5 %. The experimental findings reveal intriguing trends. Specifically, as the applied electric field's frequency increases, the dielectric constant of the PVA-Ag NPs composite decreases while the dissipation factor increases, indicative of altered electrical behavior. Furthermore, there is a noticeable augmentation in AC electrical conductivity. Notably, as the concentration of Ag NPs increases, the composite's dielectric constant and dissipation factor show a proportional rise, unveiling the interplay relationship between silver nanoparticle content and these characteristics. |
