摘要

纳米纤维具有直径小、比表面积大以及易于实现表面功能化的优点，受到广泛的关注。在众多制备纳米纤维的方法中，静电纺丝是一种高效的技术，其中同轴共纺技术由于能制备芯-壳（core-shell）结构的纳米纤维，也越来越引起人们的关注。本文介绍了基于电流体动力学的静电纺丝原理，讨论了静电纺丝相关原理研究进展，包括Taylor 锥与喷射，纳米纤维的弯曲非稳定性，高聚物溶液/熔融体流动非稳定性，两相流流型及其转换，高聚物两相流流型及其转换，非牛顿流体流动非稳定性以及两种非牛顿流体分层流动等，最后指出了尚待解决的一些问题。

Abstract

Due to tiny diameter

big specific surface area

and ability to achieve surface functionalization easily

nanofibers are attracting great attentions world widely .Electropinning is an effective method to produce continuous nanofibers

whereas more advanced coxial-electrospinning technique can be used to fabricate core-shell composite nanofibers.In this review article

the fundamental issues with electrospinning based on electrohydrodynamics are addressed .Special attention is paid to recent studies on mechanism of coaxial electrospinning .Disucssions are made on Taylor cone

two-phase flow patterns

flow instabilities

non-Newtonian properties of polymer liquids

and stratified non-Newtonian fluid flows .Several untouched matters are mentioned as well.
