Although there are many methods of fabricating nanofibres, electrospinning is perhaps the most versatile process. Materials such as polymer, composites, ceramic and metal nanofibres have been fabricated using electrospinning directly or through post-spinning processes. However, what makes electrospinning different from other nanofibre fabrication processes is its ability to form various fibre assemblies. This will certainly enhance the performance of products made from nanofibres and allow application specific modifications. It is therefore vital for us to understand the various parameters and processes that allow us to fabricate the desired fibre assemblies. Fibre assemblies that can be fabricated include nonwoven fibre mesh, aligned fibre mesh, patterned fibre mesh, random three-dimensional structures and sub-micron spring and convoluted fibres. Nevertheless, more studies are required to understand and precisely control the actual mechanics in the formation of various electrospun fibrous assemblies.
尽管制造纳米纤维有多种方法，但电纺丝可能是最通用的工艺。聚合物、复合材料、陶瓷和金属纳米纤维等材料已通过直接电纺丝或后纺丝工艺制造出来。然而，使电纺丝不同于其他纳米纤维制造工艺的是它形成各种纤维组件的能力。这肯定会提高由纳米纤维制成的产品的性能，并允许进行特定应用的改性。因此，对我们来说，了解使我们能够制造所需纤维组件的各种参数和工艺至关重要。可以制造的纤维组件包括非织造纤维网、排列纤维网、图案化纤维网、随机三维结构以及亚微米弹簧和卷曲纤维。然而，需要更多的研究来理解和精确控制各种电纺纤维组件形成过程中的实际力学原理。
