将胶原、生物玻璃和明胶按照不同的比例复合制备了一种新型复合材料,通过X射线衍射(XRD)和扫描电子显微镜(SEM)表征了生物玻璃和复合材料的结构与形貌,并研究了其机械性能和孔隙率。结果表明:复合材料的机械强度基本达到松质骨的强度需要,具有较高的孔隙率,达50%以上。该新型复合材料有望用于骨组织工程中的骨替代材料。 A novel composite was prepared by compounding collagen, bio-glass and gelatin in different proportions. The structure and morphology of bioglass and composites were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) Its mechanical properties and porosity. The results show that the mechanical strength of the composites basically meets the strength requirement of cancellous bone and has a high porosity of more than 50%. The novel composite material is expected to be used as a bone substitute in bone tissue engineering.
