In recent decades, nanofiber-based materials have been considered as one of the top interesting fundamental materials for academic studies and practical applications. However, the electrospinning, as the most popular method for manufacturing nanofibers, is plagued by its low productivity. The first patent about electrospinning was emerged in 1934 and the needleless electrospinning is regarded as one of the most promising methods to realize the high throughput of nanofibers.
This review compares the recent needleless spinning technologies from limited liquid surfaces to free liquid surfaces for improvement of nanofiber throughput. The aim of this review is to reveal the merits and drawbacks of recent methods in practical employment. The view focuses also on the future concern of the needleless electrospinning.
The current needleless electrospinning is featured with the properties: 1) high throughput; 2) lower voltage supply for the stable spinning process; 3) narrow fiber diameter distribution, followed by the drawbacks of poor long-term spinning process and limitation of a good bonding of low voltage supply.
This review provides an update on needleless electrospinning methods for high throughput of nanofibers for industrial applications.
近几十年来，基于纳米纤维的材料被认为是学术研究和实际应用中最有趣的基础材料之一。然而，作为制造纳米纤维最流行的方法，静电纺丝受到其低生产率的困扰。第一个关于静电纺丝的专利出现在 1934 年，无针静电纺丝被认为是实现纳米纤维高通量生产的最有前途的方法之一。
本综述比较了从有限液体表面到自由液体表面的最近无针纺丝技术，以提高纳米纤维的产量。本综述的目的是揭示近期方法在实际应用中的优缺点。该观点还关注无针静电纺丝的未来关注点。
目前的无针静电纺丝具有以下特点：1）高产量；2）较低的电压供应，以实现稳定的纺丝过程；3）纤维直径分布较窄，但存在长期纺丝过程不佳和低电压供应良好结合受限的缺点。
本综述提供了一种针对工业应用的高通量无针静电纺丝方法的最新进展。
