摘　　要：目的研究医用钛合金表面纳米氧化锌薄膜的制备及其抗菌性。方法二水合醋酸锌溶于无水乙醇中,利用溶胶-凝胶法在钛合金表面制备纳米氧化锌薄膜,并检测其抗菌性。结果采用溶胶-凝胶法在钛合金表面可成功制备纳米氧化锌薄膜,且薄膜对金黄色葡萄球菌和白色念珠菌的抑菌率达到92.2.%和91.4%。结论通过在医用钛合金表面制备纳米氧化锌涂层,达到良好抗菌效果。[Objective] To research the synthesis and antibacterial activity of nano ZnO thin film on medical titanium alloy. [Methods] ZnO thin film on medical titanium alloy was fabricated by sol-gel method with dissolving the Zn （CH3COO）2·2H20 in a solution of ethanol and antibacterial activity of ZnO thin film was detected. [Results] Highly quality ZnO thin film can be fabricated on medical titanium alloy by sol-gel method and the rate against staphylococcus aureus and candida albicans is respective 92.2% and 91.4%. [Conclusion] Fabricating nano ZnO thin film on medical titanium alloy can acquire better antibacterial activity.
