23 Jul Three-dimensional porous tissue engineering bracket material, preparation and application thereof
Abstract
The invention relates to three-dimensional porous engineering support material, comprising poly butylene succinate PBS and polycaprolactone PCL, wherein, the weight proportion is that the poly butylene succinate is 90 to 10 shares and the polycaprolactone is 10 to 90 shares. The invention also relates the preparation of the material, which is characterized in that the pore-foaming agent is arranged in a mold evenly and then the PBS/PLC blending chloroform solution is poured in; the support rudiment is put in a hood for 24 hours before immersing deionized water for 2 to 4 days; the PBS/PLC support material can be obtained after drying in vacuum. The invention relates to application of the material also, which mains that the material can be used as supports of bone or cartilage tissue engineered cells for repairing and restructuring the bone or cartilage tissue organ. The support material has the advantages of even inner hole structure and good communication between the holes, namely the hold diameter is between 10 to 500Mum and the porosity is between 70 to 91 percent, as well as the advantages of steady structure and easy preparation technology.
