abstract = "Electrochemical supercapacitor (EC) is a kind of device able to
generate and store clean energy, which makes it the object of
intense research. This work proposes a double layer capacitance
combination of electrochemical reduced graphene oxide (rGO) and
carbon fiber (CF) in addition to pseudocapacitive behavior of
polyaniline (PAni) to produce PAni/rGO/CF ternary composite with
high capacitive response. rGO/CF and PAni/rGO/CF are obtained by
electrochemical methodology. The morphological and structural
analyses by scanning electron microscopy, X-ray diffraction, and
Raman spectroscopy show that these nanostructured composite
materials can be produced successfully. rGO/CF and PAni/rGO/CF
samples are evaluated electrochemically by cyclic voltammetry
(CV), electrochemical impedance spectroscopy, and charge/discharge
tests. PAni/rGO/CF ternary composite presents a better performance
in terms of specific capacitance and electrochemical reversibility
than that of rGO/CF composite and CF electrodes. The results show
that this ternary composite can be a promising electrode for
applications in supercapacitors.",
