Preparation of hydroxyapatite and Properties of The composites of Hydroxylapatite/Polylactide

Hydroxylapatite with the porous structure is synthesized by the template,and we make use of XRD and SEM to show its properties.The result shows that hydroxylapatite with the porous structure is synthesized successfully by the template.Then we use the method of blend to get the Polylactide/Hydroxylapatite composites,and its bending strength and degradation behavior weretested.With the addition of hydroxylapatite,mechanical strength of the Polylactide is increased and the speed of Polylactide degradation is decreased.5% HA composites hold the most bending strength and mechanical strength.The speed of degradation for 15% HA composites is the slowest.
