▎ 摘　　要

Graphene oxide/hydroxyapatite (GO/HA) composite coatings have been fabricated by a modified electrodeposition technique on titanium substrate. The microstructure and phase constituents of the composite coatings were characterized by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman spectra. The in vitro cellular response was detected by the morphology of MG63 cells which were inoculated onto the coatings. Results show that the addition of GO into HA coatings increases the crystallinity of hydroxyapatite. In addition, in vitro cell culture assessment shows a better biocompatibility of the composite coatings compared with the pure HA coating.
