静电纺丝利用电力生产纳米级直径的聚合物纤维。当聚合物溶液或熔体表面的电力克服表面张力并导致带电射流喷射时，发生静电纺丝。当射流干燥或凝固时，带电的纤维保留下来。这种带电的纤维可以被电力引导或加速，然后收集成薄片或其他有用的几何形状。我们实验室已经对20多种聚合物进行了静电纺丝，包括聚环氧乙烷、尼龙、聚酰亚胺、DNA、聚芳酰胺和聚苯胺。大多数是从溶液中纺出的，尽管也证明了在真空和空气中从熔体中纺出。在真空中从聚合物熔体进行静电纺丝是有利的，因为可以使用比在空气中更高的场和更高的温度。
Electrospinning uses electrical forces to produce polymer fibres with nanometre-scale diameters. Electrospinning occurs when the electrical forces at the surface of a polymer solution or melt overcome the surface tension and cause an electrically charged jet to be ejected. When the jet dries or solidifies, an electrically charged fibre remains. This charged fibre can be directed or accelerated by electrical forces and then collected in sheets or other useful geometrical forms.More than 20 polymers, including polyethylene oxide, nylon, polyimide, DNA, polyaramid, and polyaniline, have been electrospun in our laboratory. Most were spun from solution, although spinning from the melt in vacuum and air was also demonstrated. Electrospinning from polymer melts in a vacuum is advantageous because higher fields and higher temperatures can be used than in air.
