Titanium alloys that are used as implant materials generally fail due to the occurrence of significant localized corrosion by interactions with corrosive body fluid. Implants also undergo loosening and detachment from the bone due to its poor biocompatibility. In this study, nano hydroxyapatite synthesized via a wet chemical method, using calcium oxide obtained from sea shells, was used to prepare a composite coating with polysulfone and was electrospun on to Ti-6Al-4V alloy. The controlling parameters of electrospinning were varied to study the characteristics of the coating followed by bioactivity studies, to ensure the biocompatibility of the coated material.
