doi:10.7517/j.issn.1674-0475.2011.04.306

Abstract

Abstract: Fe/TiO₂ films were prepared by the sol-gel and dip-coating method on glass substrate.The as-prepared samples were characterized by XRD,XPS and AFM.The influence of Fe-doping content on lattice structure and surface morphology for TiO₂ films was studied.At the same time,the antibacterial properties of E.coli of TiO₂ films doped with different iron content were also studied.The results showed that the antibacterial properties of the Fe/TiO₂ films is better than pure TiO₂ films,especially when the content of Fe-doped is 0.1%,the antibacterial properties was the best,which reached up to 98%.

Key words: Fe/TiO₂ films, sol-gel method, dip-coating method, antibacterial properties
