Advances in biomedicine and development of modern technologies in the last century have fostered the improvement in human longevity and well-being. This progress simultaneously initiated the need for novel biomaterials. Recently, degradable metallic biomaterials have attracted serious attention in scientific and clinical research owing to their utilization in some specific applications. This work investigates the effect of the polyethylene glycol (PEG) coating of open-cell iron and phosphorus/iron foams on their microstructure and corrosion properties. The addition of phosphorus causes a slight increase in pore size and the deposition of a polymer coating results in a smoothened surface and a moderate decrease in pore diameter. The PEG coating leads to an increase in corrosion rates in both foams and potentially a more desirable product.
上世纪生物医学的进步和现代技术的发展促进了人类寿命和福祉的提高。这一进展同时引发了对新型生物材料的需求。最近,可降解金属生物材料因其在某些特定应用中的使用而在科学和临床研究中引起了广泛关注。这项工作研究了聚乙二醇(PEG)涂层对开孔铁泡沫和磷/铁泡沫的微观结构和腐蚀性能的影响。磷的添加导致孔径略有增加,聚合物涂层的沉积导致表面光滑,孔径适度减小。PEG涂层导致两种泡沫的腐蚀速率增加,可能会产生更理想的产品。
