摘要
镁合金目前被认为是最理想的可生物降解金属;然而,在控制其腐蚀性和确保其生物相容性方面仍有许多障碍需要克服。在这项研究中,通过化学转化和浸渍工艺,制备了由钙离子和单宁酸(TA)组成的金属有机复合物,并将其用于镁合金涂层,然后用硬脂酸(SA)进行改性。结果表明,这种金属有机复合物涂层均匀致密,能显著提高涂层样品的耐电化学腐蚀性能和长期降解性能。因此,镁离子和钙离子的良好释放以及与骨兼容的 TA 和 SA 分子促进了成骨细胞的增殖。这种金属有机复合物涂层为镁基骨科植入物提供了一种前景广阔的改性策略。
Metal–organic complex coating for enhanced corrosion control and biocompatibility on biodegradable magnesium alloy for orthopaedic implants†
Magnesium alloy is currently regarded as the most favourable biodegradable metal; however, obstacles remain to be overcome in terms of managing its corrosion and ensuring its biocompatibility. In this study, a metal–organic complex comprising Ca ions incorporated in tannic acid (TA) was prepared and used to coat magnesium alloy by chemical conversion and dipping processes, followed by modification with stearic acid (SA). This metal–organic complex coating was demonstrated to be homogeneous and compact, and it significantly improved the electrochemical corrosion resistance and long-term degradation behaviour of the coated samples. Consequently, the well-controlled release of Mg and Ca ions, as well as the osteo-compatible TA and SA molecules, promoted the proliferation of osteoblast cells. This metal–organic complex coating offers a promising modifying strategy for magnesium-based orthopaedic implants.
