             abstract = "The carbon materials and conducting polymers are known by 
                         application in electronic devices. This work aims to study the 
                         initial steps parameters of polyaniline electrosynthesis on carbon 
                         felts annealed at 1600 K by changing the number of voltammetry 
                         cycles in aniline acid solution. The characterization was 
                         performed by Field Emission Gun Scanning Electron Microscopy, 
                         X-ray Diffraction, Infrared Fourier Transform Spectroscopy, Raman 
                         Spectroscopy and Electrochemical Impedance Spectroscopy. Under 
                         increasing number of cycles, the growth was more intense and it 
                         was easy to observe the pores clogging. Besides, it was noticed 
                         that emeraldine formation occurred progressively, from structures 
                         less to more oxidized: the polyaniline less cycled resulted 
                         closest that leucoemeraldine; polyaniline from nine cycles 
                         resulted closest to emeraldine, but all of them showed 
                         electroactive defects related to electrical charge (polarons) and 
                         conductivity (bipolarons). It was also observed that prime layers 
                         of polyaniline, formed until three cycles, followed more intense 
                         attraction of charges in solution to layer surface. This effect 
                         was emphasized from 3rd to 6th cycles.",
