In the present study, stable homogeneous dispersions of carbon nanotubes (CNTs) have been
prepared using dispersant (Sodium Dodecyl Sulfate -SDS) as dispersing agent. By applying sol-gel
method, dispersion in the hydroxyapatite matrix and its effects on the microstructure were briefly
investigated. The chemical and phase composition, structure and morphological and size analyses
were performed using XRD, SEM, TEM/SAED/EDX. The influences of different dispersing
agents (SDS) as a benchmark for future dispersion experiments and excitation wavelength are
discussed and the results are compared to the commonly used UV-Visible spectroscopic analysis.
The results indicated that synthesis of hydroxyapatite particles in the presence of the CNTs had the
best result in homogenization of the carbon nanotube dispersion and The
average crystallite size of heat-treated (at 600°C) samples, estimated by Scherrer,s equation was
found to be ~50-60 nm that confirmed by TEM.
