采用静电纺丝法制备了聚丙烯腈(PAN)/Fe3O4复合纳米纤维。实验结果表明，纺丝液中PAN和盐添加剂的浓度对纳米纤维的形态和直径有很大的影响。适当的PAN浓度和LiCl添加剂可以有效地防止静电纺丝过程中珠粒的产生，并影响静电纺丝纳米纤维的直径。纳米Fe3O4磁铁矿的掺入降低了材料的断裂强度和断裂应变。制备的PAN/Fe3O4纳米纤维在室温下具有超顺磁性。©2009 Wiley期刊公司高分子学报，2010
Polyacrylonitrile (PAN)/Fe3O4 composite nanofibers were prepared via the electrospinning of the PAN spinning solutions with magnetite Fe3O4 nanoparticles. The experimental results showed that the morphology and diameter of the nanofibers strongly depended upon concentrations of PAN and salt additives in the spinning solutions. A suitable PAN concentration and LiCl additives could effectively prevent the occurrence of beads in the electrospinning process and affected the diameters of the electrospun nanofibers. The breaking strength and breaking strain decreased when the magnetite Fe3O4 nanoparticles were incorporated. The prepared PAN/Fe3O4 nanofibers were superparamagnetic at room temperature. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
