             abstract = "The self-sustaining hybrid electrode was prepared via chemical 
                         polymerization of aniline in acid medium containing dispersed 
                         carbon nanotubes (CNT), using carbon fiber (CF) as conducting 
                         substrate. The ternary composites called PAni/CNT/CF were 
                         characterized in order to evaluate their morphologies, structures, 
                         and thermal properties. The influence of the polyaniline (PAni) 
                         layer in the ternary composite properties was studied considering 
                         different deposition times on CF samples (30, 60, and 90 min). The 
                         ternary composite morphologies were observed by scanning electron 
                         microscopy while thermal structural analyses were obtained using 
                         thermogravimetric measurements. The structural features were 
                         analyzed by Raman scattering spectroscopy and Fourier transform 
                         infrared spectroscopy (FTIR). The possible interactions between 
                         PAni and CNT were discussed on the basis of Raman and FTIR 
                         spectra. These spectroscopic analyses also confirmed that the PAni 
                         present in the composite is in the emeraldine (ES) salt form. 
                         Furthermore, the ternary composites were also evaluated by 
                         electrochemical measurements such as cyclic voltammetry (CV), 
                         galvanostatic chargedischarge, and electrochemical impedance 
                         spectroscopy (EIS) techniques. The results showed good charge 
                         storage capacity for ternary composites, in particular, for 
                         PAni/CNT/CF obtained with 90 min of deposition time, which 
                         exhibited specific capacitance of around 500 F g\−1 . 
                         Therefore, this electrode was selected to build a prototype of 
                         type I supercapacitor. This device presented specific capacitance 
                         of around 143 F g\−1 after 3200 charge/discharge cycles.",
