摘要

In the current work, (PVA-PAAm-TiC) nanocomposites films were made utilizing the casting approach with various TiC nanoparticle weight percentages (0, 2, 4, 6, and 8). Nanocomposites' structural and electrical characteristics were investigated. When the proportion is (8 wt.%), optical microscope images reveal that inside the polymers, TiC nanoparticles build a continuous network, once compared to pure (PVA-PAAm) film. The FTIR spectrum demonstrates a change in peak location in addition changes in terms of form and intensity. The surface morphology of the (PVA-PAAm-TiC) NCs films may be seen under scanning electron microscopy as several homogenous, coherent aggregates or pieces randomly scattered on the top surface. Electrical conductivity of nanocomposites in both DC and AC increases by increasing titanium carbide NPs concentrations and temperature, so that dielectric constant and dielectric loss of films are increasing with increases of titanium carbide NPs. However, the activation energy of DC electrical conductivity decreases from 0.612375 to 0.36656 eV when titanium carbide NPs concentrations reach 8%, making it suitable for many electronic approaches. Thermal energy storage, release melting and solidification periods were found to be shorter with the addition of TiC NP concentrations. According to the application findings for (PVA-PAAm-TiC) NCs, (PVA-PAAm-TiC) nanostructures were found to be effective and inexpensive for a variety of nanoelectronic applications.
