| Research Abstract |
The hydroxyapatite (HA) was grown on the surface of an individual multi-walled carbon nanotube (MWCNT), and their MWCNTs decorated with HA were sintered at 1473 K under a pressure of 80 MPa in vacuum for 90 min using a spark plasma sintering system (SPS) to produce HA/MWCNT composites. HA was partially grown on the surface of amide-functionalized MWCNTs, and the three bending strength and young’s modulus of the HA/MWCNT composites were 120 MPa and 15 GPa, respectively. As the young's modulus of the resulting composites was lower than that of the free-standing HA compacts, MWCNT were found to give the composites flexibility and to work as reinforced filler.
