摘要

在含有0.5 wt% Na2HPO4的0.5 wt% NH4F溶液中，通过阳极氧化法制备了具有生物活性的TiO2纳米管阵列。采用扫描电镜(SEM)、x射线衍射仪(XRD)对样品进行了表征。采用细菌培养试验对样品进行抑菌性能测试。Ag修饰后的二氧化钛纳米管阵列周围出现了明显的抗菌环，表明Ag修饰后的二氧化钛纳米管阵列具有良好的抗菌能力。

Fabricated Antibacterial and Bioactive Titania Nanotube Arrays Coating on the Surface of Titanium

By photic-assisted deposition, Ag nanoparticles were assembled on bioactive TiO2 nanotube arrays, which were fabricated by anodic oxidation in 0.5 wt% NH4F solution containing 0.5 wt% Na2HPO4. The samples were characterized by scanning electron mincroscope (SEM), X-ray diffraction (XRD). Germiculture experimentation was employed to testing samples’ antibacterial capability. An obvious antibacterial ring appeared around the Ag modified samples, indicating that Ag modified titania nanotube arrays has good antibacterial capability.
