Antibacterial Properties of Different Ratio Ce Doped TiO_2 Nanofibers Prepared by Electrospinning Process

摘要

The aim of this study was to prepare PVP/TiO_(2) nanofibers containing Cerium and investigate antibacterial properties of prepared nanofibers. In order to see the influence Ce doped at different ratios on the properties of TiO_(2) nanofibers, we prepared one pure TiO_(2)and Ce doped TiO_(2) nanofiber samples successfully by electrospinning method. 1, 2, 3, 4, and 5 wt% Ce doped TiO_(2) nanofibers produced at constant voltage 20 kV, constant height 8 cm and with a constant rate 0.1 mL/h. The antibacterial activities of the nanofibers were testedby usingi Staphylococcus aureus . The results showed that the antibacterial activity of TiO_(2) improves with doping of Ce. Characterization of the prepared samples was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and the differential thermal analysis/thethermal gravimetric analysis (DTA/TGA) methods.
