采用注塑方法制备了多孔纳米磷灰石/聚酰胺-6(n-HA/PA-6)复合材料,采用SEM、XRD、IR、力学性能测试考察了多孔材料的性能.结果发现:多孔纳米磷灰石/聚酰胺-6复合材料的孔隙分布均匀,贯通性良好,孔的尺寸约为100～700 靘,平均孔径约300～500 靘,大孔壁上有丰富的微孔;所得多孔复合材料的孔隙率可控,总孔隙率最高可达88.6%;多孔材料的总孔隙率降低,则开孔率随之降低;多孔纳米磷灰石/聚酰胺-6复合材料的抗压强度为1.1～15.6 MPa,压缩模量为0.4～1.4 GPa;在总孔隙率相近的条件下,多孔材料的抗压强度随n-HA质量分数增加而升高;发泡剂和发泡过程对组成纳米磷灰石/聚酰胺-6复合材料的两组元材料的性质和结构无影响.这种多孔材料可望作为人体非承重部位的植入骨修复体和组织工程支架使用.
