| Research Abstract |
Carbon nanotubes (CNTs) were soaked in 1.5 SBF in which inorganic ion concentrations are 1.5 times as high as those in body fluid. The deposition of apatite on the CNTs was investigated. So it is concluded that to make apatite deposit uniformly on the CNTs biomimeticaly in a short time, a small amount of the CNTs pre-treated with phosphoric acid or CaCl_2 solutions should be dispersed uniformly in 1.5SBF. On the other hand, fabrication of CNTs/apatite composites by sintering was investigated. Dense composites in which the CNTs were dispersed uniformly were obtained. The fracture toughness of the composites was higher, but the bending strength was lower due to the cracks inducing during firing, compared with those of conventional apatite ceramics.
