The synthesis of CNTs over hydroxyapatite by CVD and the preparation of CNTs/HA in-situ composite
Carbon nanotubes (CNTs) over hydroxyapatite (HA) as catalyst carrier were synthesized successfully using transition metal by chemical vapor deposition (CVD). The influences of catalyst types on the synthesis of CNTs were investigated when using Fe, Co and Ni as transition metal catalyst respectively. The results showed that CNTs synthesized by Fe catalyst normally possess more ideal morphology and higher crystallinity than those by the other two. But the yield rates of CNTs synthesized by CVD were in the order of Ni>Fe>Co. On the basis of this, HA matrix composites reinforced by CNTs in-situ were prepared and their mechanical properties were studied preliminarily. This study supplies valuable information for controlling the property of CNTs/HA composite by the selection of catalyst.
