Low Temperature Preparation of Thiocarbamide Doped TiO₂ Film on Stainless Steel and its Antibacterial Efficiency against Staphylococcus aureus

Abstract:

This study aimed to synthesize and then characterized the physical property of thiocarbamide (SN) doped TiO₂ thin films performance coated on stainless steel surfaces at low temperature by a rotary evaporator-assisted sol–gel process. The study also investigated the efficiency of this compound to inhibit the growth of Staphylococcus aureus. The films were analyzed using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray photo electron microscopy (XPS) and inductively couple plasma (ICP). The result of the physical properties showed the smaller size of doped compound crystal (10.3 nm.) than undoped crystal (11.0 nm.) by the x-ray refraction test. The antibacterial activities against Staphylococcus aureus (63%) under UV irradiation showed SN doped TiO₂ nano particulates film enhance bacterial inactivation within 150 minutes. The expected overall properties of nanocomposites may open the way towards new applications of high performance stainless steel, leading to an innovative product development in the hospitals, electronics for coatings and many other applications.
