Antibacterial Effect of apatite coated Titanium Dioxide for Textiles and Coating Applications

Photocatalytic activity of titanium dioxide on thin coatings of the material exhibiting self cleaning and disinfecting properties under exposure to UV radiation, have been widely acknowledged. In this study apatite-coated TiO₂ materials were evaluated in terms of its antimicrobial property both under ultraviolet (UV) and visible light. Our results demonstrate antibacterial performance of the TiO₂ against 4 types of bacteria under UV/visible light at varying extents. We also proved that this coating technique can be applied effectively to fabric surfaces since its antibacterial ability under UV/visible light remain unchanged.
