Fabrication and Characterization of (PVA-TiO2)1-x/ SiCx Nanocomposites for Biomedical Applications

Abstract

THEORETICAL and experimental studies on structural, electrical and electronic properties of (PVA-TiO2-SiC),nanocomposites for antibacterial application have been investigated with low cost, low weight and high activity for antibacterial. The (PVA-TiO2- SiC) nanocomposites were prepared with different weight percentages of Silicon Carbide (SiC) nanoparticles. Electrical properties of (PVA-TiO2-SiC) nanocomposites were studied with different temperature range. The experimental results showed that the conductivity,(PVA-TiO2- SiC),nanocomposites is increased with an increase the weight percentages of Silicon Carbide (SiC) nanoparticles. The activation energy of(PVA-TiO2-SiC),nanocomposites decreases with increase the weight percentages of Silicon Carbide nanoparticles. The total energies of the (PVA-TiO2-SiC) nanocomposites were studied by using Gaussian 09(G09) programand density functional theory (DFT) with B3LYP/6-31G) basis set, and found that the total energies decreases with the increase the number of atoms forming the nanocomposites. The (PVA-TiO2- SiC) nanocomposites tested for antibacterial applications. The results showed that the prepared nanocomposites have good antibacterial activity.
