静电纺丝法制备有序排列的纳米纤维最新进展

Recent Advance in Fabrication of Aligned Nanofibres via Electrospinning

静电纺丝法是一种制备功能材料纳米纤维的比较简单通用的方法。一般情况下制备的纤维是直径从微米到纳米尺度不等且排列无序的纤维。近年来,有序排列的纳米纤维由于其自身独特的电学、磁学以及光学等方面的物理性质,引起了人们广泛的关注。通过改变静电纺丝仪的收集极或内部电场分布,可以制备有序排列的纳米纤维。综述了近年来报道的几种收集有序排列的纳米纤维的方法。

Electrospinning is a simple and versatile technique for fabricating nanofibers from a rich variety of functional materials. The normal fabricated electrospun fibres are randomly oriented and their diameters are in the range of micrometers and nanometers. Recently, researchers have paid more attention to the aligned nanofibres because of their unique electrical, magnetic and optical properties. In this article several approaches to collecting aligned electrospun nanofibres are reviewed.
