Preparation and Property Enhancement of Hydroxyapatite/ Poly(vinyl pyrrolidone) Nanocomposites

摘要

A series of noval organic-inorganic nanocomposite materials of hydroxyapatite/poly(vinyl pyrrolidone) were synthesized by in situ copolymerization of modified inorganic nanoscale hydroxyapatite and polyvinyl pyrrolidone). The hydroxyapatite/poly(vinyl pyrrolidone) nanocomposites were characterized by scanning electronic microscope, X-ray diffraction and Fourier transform infrared analysis. The thermogravimetric analysis and differential scanning calorimetry results showed that the thermal properties of hydroxyapatite/poly(vinyl pyrrolidone) nanocomposites were significantly improved compared with the mother poly(vinyl pyrrolidone) polymers.
