Hence it is necessary to strengthen adequately the electroche-mically active sites of conducting polymers by the addition of large surface area carbon materials or carbon nanotubes (CNTs). CNTs have been attractive materials for electrodes of super-capacitors due to their high accessible surface area, high elec-tronic conductivity, chemical and mechanical stability. In order to improve the mechanical and electrochemical properties of electrodes based on conducting polymers, the composites of conducting polymers and CNTs have been synthesized for supercapacitor applications.
