| 摘 要： | 采用电沉积方法在钛表面制备氧化石墨烯-羟基磷灰石(Graphene oxide/Hydroxyapatite,GO/HA)复合涂层,通过调整GO的浓度,研究GO对所得涂层晶体结构及生物学性能的影响。采用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)仪、傅里叶变换红外光谱(FTIR)、拉曼光谱分析所得涂层的表面形貌和物相构成,用SEM观察涂层表面MG63成骨样细胞生长情况。结果表明,电沉积法可在钛表面制备GO/HA复合涂层,且随GO浓度增加,HA结晶度增加。此外,复合涂层较单纯HA涂层更能促进成骨样细胞早期粘附。

| Abstract: | In this study, graphene oxide(GO)/hydroxyapatite(HA) composite coatings have been firstly fabricated by a modified electrocodeposition 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. The addition of GO into HA coatings increased the crystallinity of hydroxyaptite. In addition, in vitro cell culture assessment shows a better biocompatibility of the composite coatings compared with the pure HA coating. |
