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

T HEORETICAL 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.
