Viscoelastic behaviour of novel PCL/hydroxyapatite nanocomposites for bone regeneration

In the frame of a project aiming to the improvement of the properties of biodegradable polyester-based devices designed for hone regeneration, we have prepared and characterized novel composites based on poly(c-caprolactone) (PCL) and nanohydroxyapatite (HA). In particular, in this paper we report the preparation. the morphology and the rheological properties of nanocomposites obtained with PCL and its less hydrophobic derivative, PCL-MAGMA [(maleic anhydride (MA)-glycidylmethacrylate (GMA)] including different amounts of nanohydroxyapatite.
