The orientation and spatial distribution of nanocrystals in the organic matrix are two distinctive structural characteristics associated with natural bone. Synthetic soft materials have been used to successfully control the orientation of mineral crystals. The spatial distribution of minerals in a synthetic scaffold, however, has yet to be reproduced in a biomimetic manner. Herein, we report using block copolymer-decorated polymer nanofibers to achieve biomineralized fibrils with precise control of both mineral crystal orientation and spatial distribution. Exquisite nanoscale structural control in biomimetic hybrid materials has been demonstrated.
纳米晶体在有机基质中的取向和空间分布是与天然骨相关的两个独特的结构特征。合成软物质已被用于成功控制矿物晶体的取向。然而，在仿生方式下，合成支架中矿物质的空间分布尚未得到重现。在此，我们报告了使用嵌段共聚物修饰的聚合物纳米纤维来实现具有精确控制的矿物晶体取向和空间分布的仿生矿化纤维。在仿生杂化材料中实现了精致的纳米级结构控制。
