Conducting Polymer /Graphene composite electrodes for supercapacitors

Graphene, as a new emerging carbonaceous material has gained a lot of attention in the past decade due to its extraordinary intrinsic properties. Conducting polymers exhibit high potential in supercapacitors because of their advantages over other electrode materials including good conductivity, flexibility, ease of synthesis etc. But both materials have some drawbacks when they merely used as electrodes. Therefore, research community has move towards composite electrodes to avoid disadvantageous realities and accomplish the best performance. This review summarizes recent development of graphene and conducting polymer (Polypyrrole and Polyaniline) based composite electrodes for supercapacitors and the comparison of their performance.
