静电纺是目前能够制备直径低至几个纳米的连续纤维的唯一方法。这种方法可适用于合成及天然聚合物、聚合物合金及载有发色团、纳米粒子或者活性剂的聚合物,也可应用于金属和陶瓷纳米纤维的制备。利用特殊的静电纺丝法,可以生产出具有复杂结构的纤维,例如皮芯纤维或者中空纤维。 Electrospinning is currently the only method capable of producing continuous fibers down to a few nanometers in diameter. This method can be applied to synthetic and natural polymers, polymer alloys, and polymers containing chromophores, nanoparticles or active agents, as well as to the preparation of metal and ceramic nanofibers. Using special electrospinning methods, fibers with complex structures can be produced, such as sheath core fibers or hollow fibers.
