Abstract
In the research, Titanium dioxide/Graphene Oxide thin films at different concentration of graphene oxide (0.0, 0.015, 0.030, 0.045 and 4.5 g/ml) were prepared by spin coating method. Characterization of the samples was performed using X-ray diffraction and Field Emission Scannig Eelectron Microscope and Atomic Force Microscope. X-ray diffraction results show that by adding the graphene oxide, the peak associated with (001) reflection is observed at the angle of 10.5°. The analysis of Eenergy Dispersive X-ray also confirms the formation of graphene oxide sheets. Considering the excellent photo catalytic and antibacterial properties of titanium dioxide, the effect of adding the different concentration of graphene oxide on these properties has been investigated. The results show that the presence of graphene oxide increases the inhibition of Escherichia coli bacterial growth.
