In vitro mineralization of bioresorbable poly(ε-caprolactone)/apatite composites for bone tissue engineering: a vibrational and thermal investigation

As regards the untreated samples, the method of synthesis utilized for preparing the composite was found to lower the crystallinity degree. The CAp component revealed to be constituted of a B-type CAp with a 3% carbonate content. After immersion in SBF solution, vibrational analysis coupled to TG revealed the deposition of a significant amount of an apatite component on the surface of the PCL/CAp composite as well as in its interior, showing a good in vitro mineralization.
