摘要

具有类似于生物组织的动态力学响应行为的人工生物材料已引起人们的广泛关注。在这项研究中,我们报道了一种基于tio2的纳米线(TiO2NWs)支架,其表现出随纳米变形循环次数和振幅变化的动态力学响应行为。研究发现,经过多次纳米变形循环后,tio2 - nws支架的弹性和黏附力显著增加。进一步的纳米摩擦实验表明,在纳米变形循环过程中,二氧化钛纳米硅支架的弹性和粘附力增加了摩擦电效应。这些特性使得TiO2NW支架在未来可以作为模拟生物组织的智能人工生物材料进行设计和应用。

Nano-frictional mechano-reinforcing porous nanowires scaffolds

Nano-frictional mechano-reinforcing porous nanowires scaffolds

Artificial biomaterials with dynamic mechano-responsive behaviors similar to those of biological tissues have been drawing great attention. In this study, we report a TiO2-based nanowire (TiO2NWs) scaffolds, which exhibit dynamic mechano-responsive behaviors varying with the number and amplitude of nano-deformation cycles. It is found that the elastic and adhesive forces in the TiO2NWs scaffolds can increase significantly after multiple cycles of nano-deformation. Further nanofriction experiments show the triboelectric effect of increasing elastic and adhesive forces during the nano-deformation cycles of TiO2NWs scaffolds. These properties allow the TiO2NW scaffolds to be designed and applied as intelligent artificial biomaterials to simulate biological tissues in the future.
