چکیده

Pure PVA/PAA polymer films, manufactured by solution casting technique, reinforced with cobalt oxide nanoparticles (CoO NPs) calcined at temperatures (800 ºC), at different weight percentages (pure, 1, 3, 5, 7 and 9) wt%. XRD analysis of the as-synthesized nanomaterial powder indicated that cobalt oxide nanoparticles were obtained at the calcination temperature (800 °C). Heat treatment promotes continued crystallization, leading to an expansion in the dimensions of nanoparticles. The electrical properties revealed a substantial enhancement in both the (ε’), (tanδ) and σ (a.c.) of the reinformed polymer blends. The thermal properties of the films reinforced with cobalt oxide nanoparticles show an increase in the thermal conductivity (K) of the prepared films with increasing reinforcement ratios.
