摘要

镁(Mg)&;其合金有利于整形外科&;心血管医疗设备制造应用,但当与该物质的水溶液和/或水饱和组织一起放入活体环境中时,具有生物降解的天然能力。镁合金在生物体内的腐蚀性主要归因于镁的过度腐蚀。镁的耐腐蚀性差会降低植入物的机械性能,并对骨代谢产生毒性影响。一种在不改变镁合金性能的情况下提高镁合金耐腐蚀性的潜在方法是通过保护性聚合物沉积涂层。此外,为了赋予镁基材料更好的机械和生物相容性,生物聚合物已被用作复合成分。这篇综述是基于这种构成镁和生物聚合物的复合材料。它们所产生的有利的机械和促骨特性以及生物相容性可能有助于临床医生解决现有的骨科相关问题。

Magnesium based alloys for reinforcing biopolymer composites and coatings: A critical overview on biomedical materials

Magnesium (Mg) & its alloys are favourable for orthopaedic & cardiovascular medical device fabrication applications, but holds a natural ability to degrade biologically when put with aqueous solution of the substances and/or water-saturated tissue in the context of a living organism. Mg alloys nature to corrode inside the living organism body is mainly attributed to the excessive rates of corrosion of Mg. Poor corrosion resistance possessed by Mg decreases the mechanical properties of the implants, and adds toxic effects on the bone metabolism. A potential method for increasing Mg alloy resistance to corrosion without changing its properties is by the protective polymeric deposit coatings. Moreover, to impart better mechanical and biocompatible aspects to Mg based materials biopolymers have been used as a composite constituent. This review is based on such composite materials constituting Mg and biopolymers. Their resulting favourable mechanical and osteopromotive properties in conjunction with biocompatibility may help the clinicians to fix the existing orthopaedic related issues.
