Abstract
Titanium and titanium alloy materials are commonly used in dental, orthopedic and craniofacial surgery. The primary reason that TI is widely used is its biocompatibility such as corrosion resistance and ability to withstand the harsh conditions within the human body. This study investigated the effects of anodization duration and voltage on the geometry of vertically oriented titanium dioxide (TiO2) nanotubes (NTs). In addition, the growth mechanism of vertically aligned TiO2 NTs was examined. The NTs were primarily grown in fluoride-based electrolyte solution, however the mechanism of formation of NTs in fluoride free solution as well as the effect of electrolyte pH on NT geometry was also be investigated. These TiO2 NTs have potential biomedical applications for orthopedic implants and drug delivery due to their semi-conductive nature, osseointegration, and antibacterial properties. Characterization of the TiO2 NTs was performed via scanning electron microscopy (SEM), x-ray diffraction (XRD) and Energy Dispersive Spectroscopy (EDX).
