Biodegradable polyester nanocomposite and preparation method thereof

The invention provides a biodegradable polyester nanocomposite and a preparation method thereof and in particular provides a compatibilizer modified polycaprolactone (PCL)/hydroxyapatite nanocomposite and a preparation method thereof. The compatibilizer can obviously improve dispersion of nano-hydroxyapatite in PCL, thus improving the mechanical properties of the nanocomposite. The compatibilizer has biocompatibility and biodegradability, thus being favorable for the nanocomposite to be applied in the biomedicine. The method for preparing the nanocomposite by adopting melt blending is simple and convenient to operate, is simple in production process and easily achieves large-scale production.
