摘要
主要介绍了自然界中几种具有多层级多孔结构和优异力学性能的生物材料,其宏观性能与其表面的多层级微纳米结构有着密切的联系。通过多层级多孔结构的构筑,生物材料不仅大幅度降低了自身的密度,同时也保持了优异的力学性能,即轻质高强、吸音降噪等。通过对生物材料多孔结构的模仿,有望为开发具有仿生多孔结构和优异性能的人工材料提供重要启示和帮助。
This paper mainly introduces several biomaterials with multi-layered porous structures and excellent mechanical properties in nature,and their macroscopic properties are closely related to the multi-layered micro-nanostructures on their surfaces.By the construction of multi-layered porous structures,biomaterials not only greatly reduce their own density,but also often maintain excellent mechanical properties,such as light weight,high strength,sound absorption and noise reduction.Through the imitation of the porous structure of biomaterials,it is expected to provide important enlightenment and to help for the development of artificial materials with biomimetic porous structure and excellent performance.
