چکیده انگلیسی
Nanofiber fabric is firstly introduced to replace common microfiber fabrics as the platform for flexible supercapacitors. Nanofiber and microfiber electrodes can be simply fabricated using a dipping process that impregnates reduced graphene oxide (RGO) nanosheets into electrospun polyamide-66 (PA66) nanofiber and microfiber fabrics. RGO nanosheets are tailored to various sizes and only RGO with a medium diameter of 250-450Â nm (denoted as M-RGO) can effectively penetrate the pores of nanofiber fabrics for constructing smooth conductive paths within PA66 nanofiber fabrics. The synergistic effect between suitable sizes of RGO nanosheets and nanofiber fabrics with a high specific area provides a symmetric supercapacitor composed of M-RGO/PA66 nanofiber fabric electrodes with high-volume and high-area specific capacitance (CS,V and CS,A, equal to 38.79Â FÂ cmâ3 and 0.931Â FÂ cmâ2 at 0.5Â AÂ gâ1, respectively), which are much larger than that of a symmetric supercapacitor composed of RGO/PA66 microfiber fabric electrodes (8.52Â FÂ cmâ3 and 0.213Â FÂ cmâ2 at 0.5Â AÂ gâ1). The effect of impregnating nanofiber fabrics with suitably sized RGO to promote CS,V and CS,A of flexible supercapacitors has been demonstrated.
