                         diamond/carbon fiber (PAni/diamond/CF) ternary composites are 
                         presented in this work, as well as the application as electrode 
                         for a supercapacitor device. Different diamond morphologies were 
                         evaluated, boron-doped nano- and microcrystalline diamond 
                         (BDND/BDD). PAni was chemically synthetized in different 
                         deposition times, from 10 to 60 min. FEG-SEM images showed 
                         differences on PAni deposition for each condition. Raman and FTIR 
                         analyses confirmed PAni formation as its conductive form. TGA 
                         analyses exhibited the samples thermal behaviors. Through 
                         electrochemical characterizations, PAni deposition time and 
                         diamond influence were studied. Diamond films improved PAni 
                         deposition and enhanced electrochemical reversibility, especially 
                         BDD. For the 10-min deposition, diamond influence was better 
                         observed, and the composites showed to be reversible even at high 
                         scan rates. However, for 60 min, the electrodes presented a much 
                         higher charge storage capacity. Therefore, BDD film with 60 min of 
                         PAni deposition proved to be the best combination, in which the 
                         composite presented a specific capacitance of 520 F g\−1 in 
                         1 mol L\−1 H2SO4. Thus, this electrode was used for the 
                         supercapacitor device assembly, exhibiting high capacitive 
                         behavior, 99% of coulombic efficiency, 83% of capacitance 
                         retention after 1000 cycles, and a tendency to stabilize 
                         capacitance along the number of cycles.",
