Abstract: TiO₂/ZrO₂ composite microemulsion was prepared by the reverse micro emulsion method and was used as precursor for the preparation of TiO₂/ZrO₂ composite film. TEM tests show that the particles of TiO₂/ZrO₂ were found in the water droplets coated by oil phase. As observed by scanning electron microscope (SEM)，the fine particles in the composite film were distributed in rod form，and the film had excellent bactericidal effect on Escherichia coli (E. coli)，with bactericidal percentage reaching 98%～99%.

摘要： 研究了采用反相微乳液法制备TiO₂/ ZrO₂复合微乳液，并以其作为前体制得TiO₂/ ZrO₂复合膜。通过对复合微乳液的透射电镜测试，结果表明TiO₂/ ZrO₂复合微粒在油相包裹的“水池”中生成。由扫描电子显微镜观察到TiO₂/ ZrO₂复合膜表面微粒以棒状形式分布，而且复合膜对大肠杆菌的灭菌率达98 %～99 %。
