| Abstract: | The CPP/PLLA composites of scaffolds for cartilage tissue engineering are fabricated by solventcasting particulate-leaching and gas foam methods and their properties of physical mechanics and degradation rate are tested in this paper. The results show that the composites possess proper porosity, good physical mechanics and degradation performance, and possess 3-D, interconnecting, micro-hole network structure. Therefore, the composites are promising scaffolds for cartilage tissue engineering. |
