Description :
Hydroxyapatite (HA) is most substantial mineral constituent of bone which has
biocompatibility and bioactivity properties. Nevertheless its mechanical properties are
not appropriate for a bone substitution. Therefore, composites that consist of HA and
biodegradable polymer are usually prepared to generate bone scaffolds. In the present
work polycarpolactone (PCL) was employed as a matrix and Hydroxyapatite nanorods
were used as reinforcement element of the composites. HA/PCL nonocomposites were
synthesized by a new in-situ sol-gel process using low cost chemicals. Chemical and
physical characteristics of nanocomposites were studied by x-ray diffraction (XRD),
Field effect scanning microscopy (FE-SEM) analyses. XRD analysis revealed that pure
hydroxyapatite with no undesirable compound phases was formed with in
nanocomposites. FE-SEM images showed dispersion of HA nanorods in PCL matrix.
