【摘要】 天然生物材料经过亿万年的进化,形成了特殊的结构,具有优异的性能。因此,从材料科学的角度认识天然生物材料的结构和性能,进而抽象出更多的材料模型用于仿生材料的研究具有十分重要的意义。梯度功能材料就是其中最成功的一种模型,并得到了广泛的应用。本工作通过对天然生物材料、梯度功能材料的组成、结构、功能关系特点的简要回顾,在此基础上,将天然生物材料的组成、结构特点与梯度功能材料设计相结合,提出生物梯度功能材料的新概念,并期望应用在医学上,达到人体硬组织等的生物性永久修复和重建的目的。更多还原

【Abstract】 Having selected and evolved for millions of years,natural biomaterials have formed special structures and possess excellent properties.So,it is very important to observe and analyze the structure and property of natural biomaterials,and to find some usable regularities to be simulated for developinp biomimetic materials. Functionally Gradient Materials(FGM)is a successful model,and it has been widely used in many fields.In this paper,the characteristics of natural biomaterials and FGM were reviewed.From the combination of composition and structure characteristics of the natural biomaterials the design of FGM stems and the new concept of biological FGM was put forward.Applying this new concept clinical medicine,the biological permanent repair and reconstruction of hard tissues will come true.更多还原
