Synthesis of poly-ε-caprolactone/hydroxyapatite composite materials by in situ and mechanical mixing methods and investigation of their physico-chemical properties

摘要

This work is dedicated both to investigation of the influence of different conditions on the molecular weight characteristics of poly-e-caprolactone(PCL)and to the synthesis of composites based on PCL and hydroxy apatite(HA)by in situ and mechanical mixing methods.It was shown that in situ synthesis is accompanied by chemical interactions between PCL and HA that were confirmed by IR spectroscopy and thermal analysis.The morphology of in situ obtained composites has more homogeneous and regular distribution of HA particles in the polymeric matrix than composites synthesized by mechanical mixing of HA and PCL.
