Abstract

In this study, porous titanium compacts obtained by the pressing-sintering route, previously modified by an anodic oxidation treatment, were coated with 3- Aminopropyltriethoxysilane (APTES) in order to facilitate a later immobilization of peptides in view of improving their biocompatibility. The surface of porous titanium before and after modification was characterized by X-ray photoelectron spectroscopy (XPS) and attenuated total refraction-Fourier transform infrared spectroscopy (ATR-FTIR). According to spectral analysis, after the bonding of APTES films on the anodized PM porous titanium surfaces, a new peak located around 1110 cm− 1 attributed to siloxane groups suggests that the silane agent had been grafted onto the surface of the modified titanium substrate. Also, after the deposition of APTES films, significant changes were seen in the XPS spectrum, as the peaks corresponding to Ti disappeared, indicating a full silane coverage on the porous surface.
