摘要
综述了贝壳珍珠层结构及其文石晶体的结晶学取向特征,并概述了珍珠层中参与调控生物矿化的有机基质的结构和功能方面的最新研究进展。从裂纹偏转、纤维拔出、有机基质桥连及矿物桥的作用等方面对珍珠层的高韧性机制进行了讨论。同时介绍了珍珠层的微结构特征及其特殊的组装方式在仿生材料制备方面的应用。
The update progress in studies on the microstructure, aragonitic crystallite orientation in nacreous layer of mollusc, and the characterization and functions of the matrix integrated in the nacre layer are reviewed. It is found that the crack deflection, fibre pull-out, organic matrix bridging and the existence of mineral bridges are the main toughening mechanisms of nacre. Additionally, the applications of the principles and mechanisms of biomineralization in mollusk shell in biomimetics for artificial synthesis materials are also discussed.
