ABSTRACT

This chapter explores the novel hydroxyapatite-based composite coatings with lignin, poly(vinyl alcohol), chitosan, and graphene deposited on titanium substrate using the electrophoretic deposition (EPD) method. Since silver nanoparticles and antibiotic gentamicin have been incorporated as antibacterial agents, these coatings are suitable for medical applications as hard tissue implants. EPD has allowed the formation of thin films of controlled thickness and morphology by changing the electrochemical deposition parameters. Based on cytotoxicity, antibacterial activity, and in vitro bioactivity testing, the evidence presented here demonstrates that hydroxyapatite-based composite coatings produced on titanium substrate by electrophoretic deposition are excellent candidates for biomedical applications.
