摘      要：A combination of carbon nanotubes （CNTs） and titanium （Ti） modified with TiO2 nanotubes （TiO2 NTs） was fulfilled with the aim of improving bioactivity of Ti ***,well-ordered TiO2 NTs were prepared by the electrochemical anodization of Ti in an ethylene glycol electrolyte containing 1 wt% NH4F and 10 wt% H2O at 20 V for 50 min,followed by ***,the carboxylated CNTs were coated onto the TiO2 NTs using electrophoretic deposition （EPD） *** growth of hydroxyapatite （HA） on the samples was investigated by soaking them in simulated body fluid （SBF）.The result showed the CNTs-coated Ti with the modification of TiO2 NTs （CNTs-TiO2 NTs） was more efficient to induce HA formation than the CNTs-coated smooth Ti （CNTs-Ti）.The vitro cell response was evaluated using osteoblast cells （MC3T3-E1）.The good cell proliferation and strong cell adhesion could be obtained on the CNTs-TiO2 *** results indicated that CNT coating on the Ti modified with TiO2 NTs could be potentially useful for the periodontal ligament combination on dental implants.
