聚酯酰胺/β-磷酸三钙共混物的制备及相容性研究

The Preparation and Miscibility of Polyesteramide/β-Tricalcium Phosphate Blends

研究了可生物降解聚酯酰胺与 β-磷酸三钙和表面接枝 β-磷酸三钙共混物的制备及其共混体系的界面相互作用 ,并用 IR,DSC及 SEM对其进行了表征。

s The polyesteramide/β-tricalcium phosphate blends were prepared from polyesteramide(PEA) and β-tricalcium phosphate(TCP) or surface grafted β-tricalcium phosphate(MTCP) by ε-caprolactone. The PEA/TCP and PEA/MTCP blends were characterized by FTIR spectra, DSC and scanning electron microscopy(SEM). The good miscibility was existed in PEA/MTCP systems according to the specific interactions between the ε-caprolactone segments of β-tricalcium phosphate surface and polyesteramide macromolecular chains.
