AZ31镁合金表面层层组装PSS/GS膜的体外耐蚀与抗菌性能(英文)
发布时间:2022-12-17 22:57
为提高镁合金的耐蚀性,并且使其表面具有抗菌功能,从而抑制生物膜的形成和生物腐蚀,利用原位水热法在AZ31镁合金基体上制备氢氧化镁膜以及层层组装制备硫酸庆大霉素(GS)和聚苯乙烯磺酸钠(PSS)多层膜。利用扫描电子显微镜、傅里叶红外光谱、X射线光电子能谱、电化学测试和浸泡实验研究(PSS/GS)nMg复合膜层的表面形貌、化学成分和耐腐蚀性能。最后,通过抑菌圈实验和平板计数法评定(PSS/GS)nMg样品抵抗金黄葡萄球菌的性能。结果表明,在镁合金表面制备的复合膜层表现出较好的耐蚀和抗菌性能。这种复合膜层可用作医疗植入器件涂层。
