Highly aligned porous biomaterials by reverse freeze casting

摘要

Highly porous materials with large, aligned, and interconnected pores were fabricated by reverse freeze casting. Migration of various metallic/ceramic powders was occurred along the boundary of camphene solid by keeping at specific temperature. The porous scaffolds with aligned pores were stronger than other porous materials with same porosity. Reverse freeze casting method can be widely applied to producing porous scaffolds for bone tissue engineering.
