Hydrothermal Synthesis of Flexible Fe‐Doped Polyaniline/Dye‐Functionalized Carbon Felt Electrode for Supercapacitor Applications

This new electrode material exhibited excellent synergetic effect between PANI and carbon felt electrode in the presence of dye molecules. A fast and simple one-step hydrothermal method was used to prepare iron doped polyaniline/Lanaset green B carbon felt electrodes. The capacitance of Lanaset Green B doped Fe-PANI electrode was 8–times higher than the Fe-PANI electrode in 3.0 M KCl electrolyte.
