             abstract = "Polyaniline was electrosynthesized using three voltammetric cycles 
                         on carbon fiber felts annealed at 1400, 1600, 2000, and 2300K. 
                         Felts and composites was characterized by scanning electron 
                         microscopy, X-ray diffraction, Raman and Fourier transform 
                         infrared spectroscopy, and electrochemical impedance spectroscopy. 
                         Annealing temperatures increasing provides more crystalline felts. 
                         The increase of capacitance is due to presence of functional 
                         groups that attract a lot of charge to double layer. Capacitance 
                         found for felts treated in 1400K is larger compared to felts 
                         treated in 2300K. The functional groups presence on annealed felts 
                         at lower temperature implies polyaniline growth in several 
                         orientations and regions, evidenced by the high heteroatoms ratios 
                         which decrease with increasing annealing temperature. Therefore, 
                         for higher temperatures, the polyaniline growth occurs at several 
                         additional orientations. The polyaniline oxidation degree was 
                         close to emeraldine allowing mobile charge presence. 
                         Electrochemical impedance spectroscopy confirmed that as 
                         temperature decreases, resistance of inner and outer double layer 
                         decreases. To 1600K annealing, polyaniline showed an increase in 
                         inner double layer capacitance which can be confirmed by lower 
                         ratio between bipolarons and polarons. The tendency to increase 
                         energy and power density is most prominent for polyaniline at 
                         2300K felt.",
