Abstract
Polyaniline (PANI) samples were synthesized onto platinum wire in HCl-based aqueous solution containing low amounts of nickel sulfate. The structural analysis of them shows increasing densification of its porous structure insofar the amount of this salt increases. This fact leads to the enhancement of its total conductance, consequently, improves the current flow. In addition, the impedance electrochemical spectroscopy shows that also the capacitances and resistances associated to the platinum/PANI/electrolyte system also undergoes modification so that the current-potential curves exhibit an increasing hysteresis, making this material an excellent candidate to be used in energy storage devices or supercapacitors.
