Abstract

Multi walled carbon nanotubes-hydroxyapatite (MWCNTs-HA) with various contents of MWCNTs was synthesized using the sol-gel method. MWCNTs-HA composites were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). HA particles were generated on the surface of MWCNT. Produced MWCNTs-HA nanocomposites were coated on pure titanium (PT). Characteristic of the titanium coated MWCNTs-HA was evaluated by field-emission scanning electron microscopy (FE-SEM) and XRD. The results show that the titanium surface was covered with MWCNTs-HA nanoparticles and MWCNTs help form the crystalized hydroxyapatite. Furthermore, the MWCNTs-HA coated titanium was investigated for in vitro cellular responses. Cell proliferation and differentiation were improved on the surface of MWCNT-HA coated titanium.

摘要

采用溶胶 - 凝胶法合成了具有不同多壁碳纳米管(MWCNTs)含量的多壁碳纳米管 - 羟基磷灰石(MWCNTs - HA)。通过X射线衍射(XRD)和透射电子显微镜(TEM)对MWCNTs - HA复合材料进行了表征。HA颗粒在MWCNT表面生成。将制备的MWCNTs - HA纳米复合材料涂覆在纯钛(PT)上。通过场发射扫描电子显微镜(FE - SEM)和XRD对涂覆有MWCNTs - HA的钛的特性进行了评估。结果表明,钛表面覆盖有MWCNTs - HA纳米颗粒,且MWCNTs有助于形成结晶的羟基磷灰石。此外,还研究了MWCNTs - HA涂覆的钛的体外细胞反应。在MWCNT - HA涂覆的钛表面,细胞增殖和分化得到了改善。
