Abstract

A new kind of Hydroxyapatite (HA) composites was fabricated using a hot-press method in which carbon nanotubes (CNTs) were introduced to the HA ceramic matrix to improve the mechanical properties of the resulting composites. The CNTs were treated using a mixture of nitric acid and sulfuric acid. A homogeneous dispersion of the CNTs in the HA matrix was achieved through dispersing them in the solution of surfactant. The bioactivity of the samples was tested. The microstructures of HA/CNT ceramic composites and the sample surfaces after immersion in SBF were characterized by SEM. The results showed that the introduction of the CNTs into HA ceramic matrix could produce positive strengthening effect without impairing the biological properties of the HA ceramic.
