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.
