NOVELTY - A producing method of a nano-ribbon graphene/polypyrrole composite comprises steps of: dispersing a nano-ribbon graphene into a hydrochloric acid to form a nano-ribbon graphene solution; uniformly dispersing a cetyltrimethylammonium bromide (CTAB) into the nano-ribbon graphene; dispersing a pyrrole monomer into the nano-ribbon graphene to form a nano-ribbon/pyrrole monomer solution; and adding a initiator into the nano-ribbon/pyrrole monomer solution to initiate a polymerization reaction of the pyrrole monomer; adding a terminating agent to the nano-ribbon/pyrrole monomer solution to terminate the polymerization reaction of the pyrrole monomer to form a nano-ribbon/polypyrrole nano solution; rising with DI water and drying with a oven to form the nano-ribbon/polypyrrole nano composite. The present invention also provides a supercapacitor which has excellent cycling performance due to the polypyrrole is a great conductive polymer and has many advantage like easy to produce, stable and environmental friendly.
