| Abstract: | TiO2 sol was prepared by sol-gel method.Nano-TiO2 thin film on ceramic surface was prepared by dipcoating techniques,which were tested using XRD and AFM,and bactericidal activity of nano-TiO2 thin film was studied by natural fell bacterium experiments and artificial fell bacterium experiments respectively.The results showed that the main type of crystallite for TiO2 was anatase and the crystallite size of TiO2 was 18.98 nm,and the surface shape was fairly uniformity.Nano-TiO2 thin film had good ability of bactericidal performance on Escherichia coli,Staphylococcus aureaus,Bacillus subtilis and Pseudomonas aeruginosa. |
