• ]. Generally, the structures of nanocomposites used in electrochemical supercapacitors can influence their capacitance, charge and discharge rates, as well as their cycle stability. In our previous work [33], the ordered porous PAN/graphene composite nanofibers (OPPGCNFs) were prepared by a modified parallel
