Project Details

Description

Numerous strategies for the surface modification of titanium (Ti) and its alloys have been proposed from the view point of improving corrosion resistance and bioactivity performance. The main intension of the project is to fabricate and evaluate the corrosion and invitro bio compatibility behavior of polymer nanocomposite coatings on newly developed Ti alloys for implant applications. In this project work, Poly (3, 4-ethylenedioxythiophene) (PEDOT) nanocomposite coatings with the different amount of hydroxyapatite nanoparticles will be deposited on Ti alloys through electrochemical route. The project will include an in-depth evaluation on the effect of the process parameters of the electrochemical method (cyclic voltameteric method) on the structure, crystallinity and surface microstructure of the investigated coatings as well as the possibility of maintaining adhesion towards Ti surface. After that, the water contact angle of the investigated coatings will be measured and correlated with the invitro biocompatibility performance. Finally, the invitro biocompatibility performance will be evaluated and the corrosion behavior of the investigated coatings will be investigated in simulated body fluid (SBF) and the comparisons will be made with uncoated as well as their pure PEDOT coating. The successful implementation of the proposed research work, if funded, would noticeable the path for more in-depth research for this advanced promising coatings materials and lead to the outline of a technological route that can be utilized to develop polymer bioactive coatings for Ti alloys for implant applications.
