【 摘 要 】

In the present study, Ag-loaded Titanium Nanotube Arrays (TNTAs) were fabricated on the surface of non-toxic dental material, Ti-6Al-7Nb. A layer of TNTAs were introduced on Ti-6Al-7Nb surface, hence extending its effective area and inducing antibacterial properties for biofilm inhibition. TNTAs were generated on the surface of Ti-6Al-7Nb by an anodization method in an electrolyte solution containing glycerol, water and NH4F. This was followed by depositing Ag via a photo-assisted deposition method to obtain Ag-loaded TNTAs. Surface morphology and crystallinity were evaluated by FESEM-EDX and XRD, respectively. FESEM-EDX analysis showed that Ag-loaded TNTAs were formed and well aligned on the surface of Ti-6Al-7Nb, while XRD confirmed the presence of anatase and Ag crystals.
