摘要

将聚氧化乙烯(PEO)水溶液在不同的工艺条件下进行电纺

制备了PEO纤维.用SEM研究了纤维的分散形态;用DSC和XRD研究了纤维的结晶性能.电纺纤维分散形态是由浓度、电压、固化距离等因素综合作用的结果.其中

浓度是最关键的因素.降低溶液浓度

提高静电压和增加固化距离均会使纤维变细.电纺得到的纤维与原粉相比

电纺使纤维结晶度下降

理论上分析了可能的机理.

Abstract

PEO solutions were electrospun under different technological conditions to prepare superfine nanofibers Dispeming morphology of electrospun fibers was characterized by SEM

and crystallization behavior of electmspun fibers was characterized by DSC and XRD Dispersing morphology of electrospun fibers was affected by the solution concentration

the voltage and the distance between two electrodes．In all parameters

the concentration was the key factor Electmspun fibers gradually became fine when the concentration was reduced

and/or the voltage and the distance between two electrodes was increased．The crystallinity of PEO electrospun fibers was lower than that of PEO powders

and the possible mechanism was analysed．
