采用搅拌铸造和挤压法制备mg/ha复合材料,并在其表面采用静电纺丝法涂覆聚己内酯/羟基磷灰石(PCL/ha)纤维(2.5%和5%ha,质量分数),以提高其耐腐蚀性。力学性能测试结果表明,复合材料的压缩屈服强度从73mPa.纯镁)提高到151mPa.提高了107%。SEm、edS和XRD分析表明,ha颗粒分布在多孔涂层中。极化曲线结果表明,涂层试样的耐腐蚀性能均优于未涂覆试样。PCL涂层使样品的腐蚀电流密度降低了两个数量级。通过极化和体外腐蚀试验证明了ha在涂层中的有效性。涂层和随后形成的Ca.P层阻碍了模拟体液与基体的接触和渗透,从而起到保护表面的作用。PCL/2.5%ha涂层样品的腐蚀速率最低,其平均值为0.98mm/a.与未涂层样品相比,在14天内减少了81%。根据3天mTT结果,使用PCL/2.5%ha涂层可使细胞活性从43%提高到121%。综上,涂覆PCL/2.5%ha纤维的mg/ha复合材料在生物可吸收植入物方面具有广阔的应用前景。
