采用静电纺丝和气相聚合相结合的方法制备了聚（3，4-乙撑二氧噻吩）（PEDOT）纳米纤维。纤维具有约350 nm的直径，并且在大多数交叉处被焊接，从而为垫提供强的尺寸稳定性。由于静电纺丝毡的超多孔性质，静电纺丝毡表现出非常高的电导率（60 +/- 10 S cm（-1），这是迄今为止报道的聚合物纳米纤维的最高值）以及改进的电化学性质。这些垫子被整合到全纺织柔性超级电容器中，使用碳布作为集电器，电纺聚丙烯腈（PAN）纳米纤维膜作为隔板。将织物层堆叠并嵌入含有离子液体和作为主体聚合物的PVDF-共-HFP的固体电解质中。由此产生的超级电容器是完全灵活的，并在环境条件下表现出有趣和稳定的性能。皇冠版权所有（C）2010由爱思唯尔B.

Poly(3,4-ethylenedioxythiophene) (PEDOT) nanofibers were obtained by the combination of electrospinning and vapor-phase polymerization. The fibers had diameters around 350 nm, and were soldered at most intersections, providing a strong dimensional stability to the mats. The nanofiber mats demonstrated very high conductivity (60 +/- 10 S cm(-1) the highest value reported so far for polymer nanofibers) as well as improved electrochemical properties, due to the ultraporous nature of the electrospun mats. The mats were incorporated into all-textile flexible supercapacitors, using carbon cloths as the current collectors and electrospun polyacrylonitrile (PAN) nanofibrous membranes as the separator. The textile layers were stacked and embedded in a solid electrolyte containing an ionic liquid and PVDF-co-HFP as the host polymer. The resulting supercapacitors were totally flexible and demonstrated interesting and stable performances in ambient conditions. Crown Copyright (C) 2010 Published by Elsevier B.V. All rights reserved.
