A New Approach for the Synthesis of Nanostructured Polyurethane-Hydroxylapatite-based Hybrid Materials
The structural properties of composites prepared by a hydrothermal method in high-pressure conditions and the role of pressure in the formation of hydroxylapatite-polyurethane (HAp-PU) materials with strong interactions between the two components were investigated. X-Ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), FT-IR and NMR analyses were used to characterize the composite powders from a structural, morphological and compositional point of view. Both FT-IR and NMR spectroscopies indicate interactions between hydroxylapatite and acid polyurethane
