摘要
近年来组织工程以及机器人等领域对三维微纳结构的需求日渐增长,利用熔体电纺射流较长的直线段,通过对熔体电纺工艺的改进可以制备有序排列的纤维结构。本文简述了熔体电纺可控成型的原理,介绍了通过熔体电纺不同的工艺方法获得的一维、二维以及三维的有序纤维结构,指出熔体电纺可控成型应对纺丝工艺进行进一步优化,并研究其中的静电排斥机理,从而获得具有更高精度和力学性能的三维微纳结构,拓展其应用领域。
Over the last decade, the demand for 3D micro-nano structures in the fields of tissue engineering and robotics has been increasing. And orderly arranged three-dimensional structure could be prepared by improving the melt electro-spinning process. This paper describes the principle of controlled molding via melt electro-spinning, and summarizes different melt electro-spinning techniques for obtaining ordered fiber structure. Then it points out that it is necessary to further optimize the melt electro-spinning process, and investigates the mechanism of electrostatic repulsion to obtain three-dimensional micro-nano structures with higher accuracy and better mechanical properties, so as to expand their application fields.
