静电纺丝是从不同聚合物和聚合物共混物的溶液制备亚微米纤维的相对简单的方法。如果溶液是绝对绝缘的，或者施加的电压不够高，静电力不能克服表面张力，那么静电纺丝就不能生产纤维;但是，如果在溶液中加入一些盐，这个问题就可以克服。研究了不同盐对聚丙烯腈（PAN）聚合物溶液静电纺丝的影响。实验中所用的无机盐包括LiCl、NaNO 3、NaCl和CaCl 2。结果表明，在不同浓度的PAN溶液中分别加入这些无机盐时，电导率的大小顺序为LiCl > NaNO 3> CaCl 2> NaCl >不加盐。盐的加入对纺丝液的粘度和剪切强度影响较小，主要受PAN纺丝液浓度的影响。不同盐溶液所纺纳米纤维的直径大小顺序为：LiCl > NaNO 3> CaCl 2> NaCl。© 2006 Wiley Periodicals，Inc.应用聚合物科学杂志103：3865-3870，2007
Electrospinning is a relatively simple method to produce submicron fibers from solutions of different polymers and polymer blends. If the solution is absolutely insulating, or the applied voltage is not high enough that electrostatic force cannot overcome the surface tension, then no fiber can be produced by electrospinning; however, if some salt is added in the solution, the problem can be overcome. The effect of different salts on electrospinning of polyacrlonitrile (PAN) polymer solution was investigated in this article. The various inorganic salts used in this work include LiCl, NaNO3, NaCl, and CaCl2.The results show that when the salts were added, respectively, into different concentrations of PAN solution, the order of conductant was LiCl > NaNO3 > CaCl2 > NaCl > no salt added. Viscosity and shearing strength of electrospinning solutions are slightly affected by the adding of salts and mainly affected by the changes in concentration of PAN electrospinning solutions. The diameter of nanofibers electrospun by solutions with different salts size down as follows: LiCl > NaNO3 > CaCl2 > NaCl. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 103: 3865–3870, 2007
