Abstract:
A hydroxyapatite ceramic hybrid material includes a hydroxyapatite ceramic structure having pores therein and a biodegradable polymer included in the pores in the hydroxyapatite ceramic structure. The biodegradable polymer can be a poly L-lactic acid polymer. A method for preparing a hydroxyapatite ceramic-biodegradable polymer hybrid material includes preparing a porous hydroxyapatite ceramic containing pores having an average pore diameter of 10 μm or larger; and forming a biodegradable polymer in the pores of the porous hydroxyapatite ceramic. The porous hydroxyapatite ceramic may be prepared by: preparing a slurry comprising hydroxyapatite fibers and heat-degradable particles in a selected solvent; filtering the slurry to obtain a paste; preparing a molded body using the paste; compacting the molded body to produce a green compact; and firing the green compact at a temperature at least 1000° C. to produce a porous hydroxyapatite ceramic structure.
