다국어 초록 (Multilingual Abstract)
This study was performed to improve surface properties of anodized titanium nanotubes. The glycerol solution containing 1 wt% NH4F and 20 wt% deionized water was used as an electrolyte. Pulse signals with a potential of 20 V and current density of 20 ㎃/㎠ were applied for 40 minutes. TiO2 nanotubes were heat-treated at 500℃ for 2 hours and precalcified by soaking in Na2HPO4 solution for 24 hours and then in saturated Ca(OH)2 solution for 5 hours. To evaluate the bone conduction of precalcified TiO2 nanotubes, hydroxyapatite precipitation was investigated in a simulated body fluid (SBF) with pH 7.4 at 36.5℃ for 10 days.
The results obtained were summarized as follows;
1. Two size of TiO2 nanotubes with 97.4±17.6 ㎚ and 40.8±15.2 ㎚ in diameter were fabricated by anodization.
2. The concentration of F ion in TiO2 nanotubes was relatively high but was removed after heat-treatment at 500 ℃.
3. The bone conduction of TiO2 nanotubes was more enhanced by precalcification treatment in the solutioncontaining Ca2+ and PO43- ions.
4. MC3T3-E1 mouse osteoblast cell adhesion was more enhanced in precalcified TiO2 nanotubes compare to polished titanium.
The results obtained were summarized as follows;
1. Two size of TiO2 nanotubes with 97.4±17.6 ㎚ and 40.8±15.2 ㎚ in diameter were fabricated by anodization.
