植酸镁（Magnesium phytate）是一种在生物医学领域具有重要价值的表面改性材料，尤其适用于可降解金属植入物的功能化涂层构建。通过与羟基磷灰石复合，植酸镁（Magnesium phytate）能够显著改善植入材料的耐腐蚀性与生物活性。镁基材料因其优异的力学性能和生物相容性被视为理想的体内可降解植入物，但其在含氯离子的体液环境中易发生过快降解，可能导致植入体早期失效或局部离子浓度过高引发溶骨反应。表面改性技术如微波辅助法可高效制备复合涂层，其中单一的植酸涂层虽能增强基材结合力，但存在易开裂、保护周期短及缺乏生物活性等问题。羟基磷灰石作为人体骨骼的主要无机成分，能有效促进骨整合与新生骨形成。将植酸镁（Magnesium phytate）与羟基磷灰石复合后，不仅显著延长了对基材的腐蚀防护周期，弥补了单一涂层的机械缺陷，更通过赋予涂层优异的生物活性，实现了植入体在人体内安全降解与高效成骨的双重目标，为可降解植入材料的临床应用提供了关键技术支持。

Magnesium phytate is a valuable surface modification material in the biomedical field, particularly suitable for constructing functional coatings for degradable metal implants. By combining with hydroxyapatite, magnesium phytate can significantly improve the corrosion resistance and bioactivity of implant materials. Magnesium-based materials are considered ideal biodegradable implants due to their excellent mechanical properties and biocompatibility. However, they are prone to rapid degradation in chloride-containing body fluids, potentially leading to premature implant failure or osteolysis caused by localized high ion concentrations. Surface modification techniques, such as microwave-assisted methods, can efficiently prepare composite coatings. While single phytate coatings can enhance substrate adhesion, they suffer from cracking, a short protection period, and a lack of bioactivity. Hydroxyapatite, as a major inorganic component of human bone, effectively promotes osseointegration and new bone formation. The combination of magnesium phytate and hydroxyapatite not only significantly extends the corrosion protection period of the substrate, compensating for the mechanical limitations of a single coating, but also, by imparting excellent bioactivity to the coating, achieves the dual goals of safe implant degradation and efficient osteogenesis in the human body, providing key technical support for the clinical application of biodegradable implant materials.
