Abstract

Ag-TiO₂ nano-composite coatings showed the synergistic effect on the anti-bacterial activity. However, little was known on the mechanism of the enhanced anti-bacterial effect. In this paper, a range of Ag-TiO₂ nano-composited coating with different TiO₂ contents were prepared on titanium substrate using an electroless deposition technique and the antibacterial performance of the coatings were evaluated with E.coli and S.aureus. This work demonstrated for the first time that the incorporation of TiO₂ nano-particles into Ag matrix not only significantly promoted the Ag ion release, but also significantly increased the electron donor surface energy, which lead to the enhanced antibacterial effect of the Ag-TiO₂ coatings.
