摘　　要：纳米多孔金属因其特殊的结构带来的优异性能,在催化和能源等领域得到了广泛的应用。在医用植入领域,具有微/纳米尺度双连续多孔结构的仿生材料也逐渐引起重视,但目前传统的成型工艺很难实现该类结构的制备。近年来,由于纳米多孔金属与人体骨骼中的多孔结构类似且具有良好的综合性能,开始被尝试引入医用植入领域以获得新型金属植入材料。现有研究发现,纳米多孔结构的金属材料在力学与生物学上均有着相对较好的性能表现,故在植入领域有着极大的应用潜力。聚焦于脱合金制备纳米多孔金属,系统综述了该类纳米多孔金属在植入领域的研究进展。首先介绍了常见的金属植入材料,然后重点阐述了脱合金法制备纳米多孔金属植入材料的具体制备工艺,并基于所制备的纳米多孔金属具有的结构特征列举了该类结构金属在植入领域的具体应用形式,最后对纳米多孔金属在植入领域的发展前景进行了展望。Nanoporous metals have been widely used in many fields containing catalysis and energy owing to their unique structural characteristics.In medical implant field,the biomimetic materials with bicontinuous porous structure at the micro/nanoscale have attracted much attention,but the traditional forming methods are hard to achieve this structure.In recent years,due to the excellent performance and similarity with the porous structure in human bones,nanoporous metals have been introduced into the implant to obtain new metallic implant materials.Previous studies have found that metallic implant materials with nanoporous structure exhibit relatively good performance in mechanics and biology,and have great application potential in the field of implantation.In this work,the research status of the nanoporous metals prepared by dealloying techniques for implantation application is systematically reviewed.Firstly,the common metallic implant materials are introduced,then the basic preparation techniques and specific application forms of nanoporous metallic implant materials prepared by the dealloying method are emphatically described,and finally,their development prospects is discussed as well.
