静电纺丝的过程产生直径范围从微米到纳米尺度的聚合物纤维。当生产纤维时，它们通常被纺丝并收集在缺乏结构取向的随机垫中。在一些应用中，人们对纳米纤维的平行排列感兴趣，以产生具有独特的电学、光学和机械性能的结构。提出了一种简单而成功的方法，用于纺制具有一厘米宽的取向纳米纤维条的片材。该技术使用以圆形鼓的形式均匀间隔的铜线作为电纺纳米纤维的收集器。该方法可以很容易地收集对齐的底片，而不会干扰对齐的结构，并且该方法是鲁棒的。
The process of electrospinning produces polymeric fibers with diameters ranging from the micrometer to the nanometer scale. As the fibers are produced, they are usually spun and collected in a random mat lacking structural orientation. In some applications there is interest in parallel alignment of nanofibers to produce structures with unique electrical, optical, and mechanical properties. A simple and successful method for spinning sheets with one centimeter wide strips of aligned nanofibers is presented. The technique uses copper wires spaced evenly in the form of a circular drum as a collector of the electrospun nanofibers. Aligned nanofiber sheets can be collected easily without disturbing the aligned structure, and the method is robust.
