Abstract

Effects of SiO 2 surface-modification on Ti-6Al-4V as dental implant materials have been studied. Prior to modification using SiO 2 , TiO 2 nanotubes were generated on the surface of Ti-6Al-4V which is expected to improve the antibacterial properties. SiO 2 /TiO 2 nanotubes were synthesized via an in-situ anodization process, employing Ti-6Al-4V as the working electrode. TEOS was used as SiO 2 precursor and the electrolyte solution used was a mixture of glycerol, NH 4 F, H 2 O, and TEOS. The amount of TEOS was varied at 1, 3 and 5 %v/v. FESEM-EDX analysis showed that SiO 2 was uniformly dispersed on modified Ti-6Al-4V surface. XRD analysis showed that the presence of SiO 2 did not significantly affect the crystallite size of TiO 2 anatase, revealing crystallite size of 29 and 28nm for TiO 2 and SiO 2 /TiO 2 nanotubes, respectively. FTIR analysis showed the presence of Ti-O-Si bond at 982cm -1 indicating an interaction between SiO 2 and TiO 2 . Hydrophilicity of TiO 2 nanotubes were increased with SiO 2 concentration, as indicated by decreasing contact angle down to nearly 0° in the use of sufficient amount of SiO 2 on TiO 2 nanotubes. The increase of hydrophilicity due to addition of SiO 2 to TiO 2 nanotubes is expected to facilitate cell growth rate in dental implant applications.
