| Abstract | Dental implants are usually made from commercially pure titanium or its alloys. The aim of this research was to evaluate the influence of the ethanol addition in 1 M H3PO4 as an electrolyte on hydrophilicity of the anodized films. Ti-6Al-4V alloy plates were modified using two-step anodization at a low current density of 2 mA cm-2 in 1 M H3PO4 with addition of used as an electrolyte. Surface oxide properties were characterized by using various surface analytic techniques, including Field Emission Scanning Electron Microscope (FE-SEM), Atomic Force Microscope (AFM), X-ray photoelectron spectroscopy (XPS) and contact angle measurement. The non-treated Ti-6Al-4V and the anodized films formed by one-step anodization were used as control samples. A significant increase in hydrophilicity (p<0.05) was observed on the anodized films formed in H3PO4 with addition of 80%v/v ethanol via two-step anodization due to the formation of rough surface, hydroxyl groups (OH-) and adsorbed molecular water (H2O). The enhanced hydrophilicity could be explained by both the surface chemistry and surface topography of the anodized films. |
