Conducting polymers have several properties that make them useful as aerospace materials, including low density, moderate cost, excellent corrosion resistance and high conductivity. Due to its high intrinsic conductivity, thermal stability, high energy density, as well as its viability in synthetic approaches, Polypyrrole (PPy) was one of the most studied polymer-based conductive electrode materials for batteries and supercapacitors.In this work, a light flexible electrode composed of PPy electrodeposited on a carbon fiber surface was obtained electrochemically using an efficient one-step procedure, through a galvanostatic method. All the Polypyrrole in this work was obtained by electrosynthesis in structural carbon fiber. PPy deposition was performed by electrosynthesis in a three electrode cell from 0.1 molL-1 of freshly distilled pyrrole solution with 0.5 molL-1 sulfuric acid.The working electrode for the deposition of PPy was a 5 cm "smooth" Hexcel 282-50 GRAPHITE carbon fiber cable with 3000 filaments of 7.1 µm in diameter.The electrodes were morphologically characterized by Scanning Electron Microscopy. The composition and structure of the electrodes were characterized by Raman, FTIR and XRD. In addition, the capacitive performance of the electrodes was investigated by Cyclic Voltammetry; Galvanostatic Charge-Discharge and Electrochemical Impedance Spectroscopy, performed with in the potential window of -0.2 to 1.2V (vs. Ag / AgCl) in electrolyte 1.0 mol.L-1 of H2SO4, as a scan rate at 10mV.s-1 . Therefore, it was found that the carbon fiber material coated with PPy exhibited much more pronounced electroactivity than the pure carbon fiber electrode, including excellent fiber-polymer interaction. As shown in Figure 1, the CV curves of the PPy electrode, compared to the carbon fiber not coated with PPy, indicate its highly capacitive behavior. As shown in Figure 2, the growth morphology of PPy on carbon fiber is represented by a very thin film on its surface and between monofilaments, composed of numerous agglomerated and tiny nanoparticles that form a relatively dense structure. As shown in Figure 3, the high frequency EIS of the pure carbon fiber electrode exhibits greater resistance to charge transfer compared to the PPy electrode [9]. In addition, the greatest resistance related to the material at low frequencies is that of the pure carbon fiber electrode. These significant improvements in the electrochemical properties of the PPy electrode can be attributed to its improved conductivity due to the conductive carbon fiber substrate and the electrode and electrolyte contact, in addition to its porous structure and large surface area.
