Preparation and Characterization of Porous β-TCP/PLLA Composites with High β-TCP Content

Abstract:

Porous β-tricalcium phosphate (β-TCP)/ Poly L-lactic acid (PLLA) composites were prepared by thermally induced phase separation method. The results showed that the composite had an interconnected pore structure with ～200μm macropores. The inorganic particle content in the composites varied from 50% to 80% and these particles were homogeneously dispersed in PLLA matrix. The composites obtained in this study could act as a promising scaffold for bone tissue engineering because of the pore structure and the mechanical properties.
