β-TCP/CS composite scaffolds were prepared using the freeze-extraction and freeze-gelation methods.SEM,XRD,FT-IR and omnipotence material testing machine were employed to characterized the β-TCP/CS composite scaffolds.It was shown that the porosity of the β-TCP/CS composite scaffolds is above 85% and decreased with the increase of the β-TCP content.The β-TCP/CS had highest compress strength(1.73MPa) when the β-TCP content is 70%.Meanwhile,the SEM results showed that the β-TCP/CS composite scaffolds had the porous structure with the pore size from 200 to 500μm when the CS/β-TCP ratio was 30∶70.Mouse MC-3T3-E1 cells were seeded onto the surfaces of the β-TCP/CS composite scaffolds.After 7d of culture,it was shown that the cells attached,growthed and proliferated well on the surface,which implied that the β-TCP/CS possessed good cytocompatibility.
