Porous carbons are extensively studied as electrode materials for double layer capacitors due to their large surface area, chemical stability, easy processability and long cycle life. These porous materials can store electrical energy mainly in an electrostatic way, similarly to negative or positive electric charges on the plates of a capacitor. It is important to remark that porous carbon materials can also present a pseudo-capacitive behaviour due to redox processes undergone by surface functional groups, but this contribution is not as important as the one related to the double layer charge. On the other hand, conducting polymers are able to store energy through their redox processes. These polymers can be considered as potential candidates for electrochemical capacitor materials because they present a continuous range of oxidation states with increasing electrode potential, thus presenting a pseudo-capacitative behaviour . Taking into account the positive and negative features shown by both porous carbon materials and conducting polymers, it is reasonable to develop a polyaniline/carbon composite which could improve the performance of supercapacitors, taking advantage from both, the double layer mechanism provided by porous carbon materials and the pseudo-capacitative contribution from conducting polymers. Besides, carbon materials improve mechanical properties and stability of the original polymer matrix.
