摘　　要：选取聚丙烯腈(PAN)/二甲基乙酰胺(DMAC)溶液进行静电纺丝,用添加不同质量分数的氯化锂(LiCl)来控制纺丝液的导电性.理论分析与实验同时表明,在带电射流的运动过程中,含有高含量氯化锂的电势下降比含有低含量氯化锂的要快.前者引起射流的不稳定性提早发生,并且引起射流的不稳定长度减小.Polyacrlonitrile（PAN）/DMAC solution is used to study the effect of the conductance of solution on electrospinning by adding different contents of LiCl. The theory analysis and the experimental data all show that the electricity potential with high content of LiCl descends more sharply than that of low content LiCl during the charged fibers moving. The former caused jet instability to occur earlier and also caused the stablility length of electrospinning jet to decrease.
