Characterization of Hydroxyapatite synthesized from Sea shells and Electrospin Coating of Hydroxyapatite for Biomedical Applications

摘要

This study presents wet chemical reaction synthesis of nano Hydroxyapatite (HA) particles from sea shells and the use of HA particles for the preparation of a composite coating with Polysulfone (PSU), a biocompatible polymer which is electrospun on to Ti-6A1-4V alloy. The X-Ray Diffraction (XRD)/Energy Dispersive X-ray Spectroscopy (EDS) patterns obtained for the synthesized powder showed phase pure HA and the High Resolution Scanning Electron Microscopy (HR-SEM) analysis revealed that the HA particles have rod-shaped morphology. The HA particles were reinforced with PSU under different concentrations and coated by electrospinning over 2 mm thick sheets of Ti-6A1-4V alloy. The coated titanium sheets were also characterized by HRSEM.
