在苯胺与无机酸或有机酸的水溶液中，采用无模板法在不同活性基底上制备了聚苯胺纳米纤维。系统地研究了聚合电位、施加电位技术、电解液组成、聚合温度等实验参数对聚苯胺纳米纤维形貌的影响。所获得的聚苯胺纳米纤维在超级电容器中具有很好的应用前景，其比电容高达1.21 × 10（3）F/g，这是使用硫酸（1.00 M H2SO 4）作为电解质的最高值。此外，还对聚苯胺纤维的形成机理进行了探讨。
Polyaniline (PANI) nanofibers were prepared electrochemically by a template-free method on different active substrates in aqueous solutions containing aniline and inorganic acid or organic acid. The influences of experimental parameters, such as polymerization potential, techniques of applied potential, electrolyte composition, and polymerization temperature, on the morphologies of the PANI nanofibers were systematically investigated. The PANI nanofibers obtained have promising applications in supercapacitors whose specific capacitance is as high as 1.21 X 10(3) F/g, which is the highest value possible using sulfuric acid (1.00 M H2SO4) as electrolyte. In addition, the formation mechanism of PANI narrofibers is discussed.
