Synthesis of (PVA-PEG-PVP-TiO_2) Nanocomposites for Antibacterial Application

摘要

Films of (PVA-PEG-PVP) blend and (PVA-PEG-PVP-TiO_2) nanocomposites were prepared by casting method with different concentration of titanium oxide nanoparticles. These nanocomposites have good antibacterial application. The dielectric properties were measured the frequency range 100 Hz-5 MHz at room temperature. The results show that the dielectric constant, dielectric loss and A.C electrical conductivity increase with the increase of titanium oxide nanoparticles concentrations. The dielectric constant, dielectric loss decrease with the increase of frequency of applied electrical field. The A.C electrical conductivity increase with the increase of frequency.
