Abstract

Titanium and its alloys are widely used in load-bearing implants as a result of their excellent mechanical properties and corrosion resistance. In order to improve their performances with respect to osseointegration, the useof bioactive coatings has been suggested. Polypyrrole (PPy) has been chosen as coating polymer because of its ability to be electrochemically grown directly onto metallic substrates, of any shape and dimension, leading to remarkably adherent overlayers. This polymer, in addition to protecting the metal implant against corrosion, could be surface modified with biologicallyactive molecules able to stimulate positive interactions with bone tissue. In this work, PPy electrosynthesis on both titanium and Ti-Al-V substrateshas been investigated. The chemical composition and the morphology of the polymeric films, deposited under different conditions, were evaluated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM), respectively.
