Analysis of Structural, Electrical and Electronic Properties of (Polymer Nanocomposites/ Silicon Carbide) for Antibacterial Application

THE structural, electronic and D.C electrical properties of (PVA-MgO-SiC) nanocomposites for antibacterial application have been investigated. The prepared nanocomposites have low cost, flexible and high antibacterial activity. The (PVA-MgO-SiC), nanocomposites were prepared with different weight percentages of Silicon Carbide (SiC) nanoparticles. Electrical properties of (PVA-MgO-SiC) nanocomposites were studied with different temperature. The experimental results showed that the conductivity of (PVA-MgO-SiC), nanocomposites is increased with increase the concentration of Silicon Carbide (SiC) nanoparticles. The activation energy of (PVA-MgO-SiC) nanocomposites decreases with increase the weight percentages of Silicon Carbide nanoparticles. The total energies of the (PVA-MgO-SiC) nanocomposites were studied by using Gaussian 09 (G09) program and density functional theory (DFT) with B3LYP/6-31G) basis set. The total energies decreases with the increase the number of atoms forming the nanocomposites.
