This work demonstrates the facile preparation of one-dimensional nanostructures of poly(N-methyl pyrrole) (PNMPy) with the guidance of anionic organic dyes, methyl orange (MO) or Acid Blue 25 (AB). The addition of MO dye to polymerization mixture resulted in a nanotubular morphology of PNMPy, whereas nanofibers were obtained with AB dye. In order to examine the effects on yield and conductivity of the obtained polymers, various concentrations of dye ranging from 5 mM to 40 mM with fixed molar ratio of the N-methyl pyrrole to oxidant were used. Addition of both the dyes showed enhancement in the conductivity of PNMPy by one order of magnitude independent on the dye concentration. FTIR and Raman spectroscopies were used to investigate the molecular structure of PNMPy and the possible interaction with dyes. Additionally, the enhanced specific surface areas were attained for both PNMPy nanotubes and nanofibers. The presence of either dye, displayed a pronounced effect on electrochemical activity, as higher gravimetric capacitances were achieved by 1-D nanostructures.

这项工作展示了在阴离子有机染料甲基橙 (MO) 或酸性蓝 25 (AB) 的指导下轻松制备聚 ( N-甲基吡咯) (PNMPy)的一维纳米结构。将 MO 染料添加到聚合混合物中导致 PNMPy 的纳米管形态，而纳米纤维是用 AB 染料获得的。为了检查对所得聚合物的产率和电导率的影响，染料的不同浓度范围为 5 mM 至 40 mM，具有固定的N-摩尔比使用甲基吡咯作为氧化剂。两种染料的添加显示 PNMPy 的电导率提高了一个数量级，与染料浓度无关。FTIR 和拉曼光谱用于研究 PNMPy 的分子结构以及与染料的可能相互作用。此外，PNMPy 纳米管和纳米纤维都获得了增强的比表面积。任何一种染料的存在都对电化学活性有显着影响，因为一维纳米结构可以实现更高的重量电容。
