Preparation of Hydroxyapatite/Polylactide Bicomposites by Absorption Process in Liquid Phase

The hydroxyapatite/polylactide biocomposites were prepared by absorption process in liquid phase. The method avoided many disadvantages, such as interfusion of chemical impurity substances, nonuniformity dispersal of HA in PLA, low molecular weight of PLA. HA particles were uniformly dispersed in PlA matrix,and shawed well adhesion with PLA matrix. The biocomposites have the higher mechanical properties and suitable decomposable capability.
