一个增强的大分子纳米纤维网络及其意义已经开发利用其形成的理解，重点是其拓扑方面。以琼脂糖水溶液为例，利用场发射扫描电镜技术与快速冷冻干燥相结合，首次清晰地观察到了软功能材料的大分子纳米纤维网络。系统动力学研究和图像证据表明，琼脂糖等软功能材料中的纳米纤维网络是通过自外伸成核控制过程形成的。这种新的认识使我们能够通过纳米纤维网络架构来设计软材料的超功能，从而开辟了纳米制造的新方向。
An enhanced macromolecular nanofiber network and its implications have been developed by employing the understanding of its formation with an emphasis on its topological aspect. Using agarose aqueous solution as a typical example, the macromolecular nanofiber network of soft functional materials has been clearly visualized for the first time using the developed technique of field emission scanning electronic microscopy coupled with flash-freeze-drying. Both the systematic kinetic study and the image evidence indicates that the nanofiber network in soft functional materials such as agarose turns out to form through a self-expitaxial nucleation-controlled process. This new understanding enables us to engineer ultra functions of soft materials via nanofiber network architecture, which in turn opens up a new direction in nano fabrication.
