Abstract:In this paper， GO/CNTs/CNF films were prepared by the method of mechanical blending combined with vacuum filtration with nanocellulose fibril （CNF） as the substrate， and graphene oxide （GO） and carbon nanotubes （CNTs） as the active substances. The reduced graphene oxide （RGO）/CNTs/CNF flexible electrode materials （referred to as RCC electrodes） were produced by hydroiodic acid reduction， and the effects of GO dosage on the electrochemical performances of RCC electrode were investigated. The results showed that CNF could disperse GO and CNTs well， and hydroiodic acid could effectively reduce GO to RGO， and the electrochemical performances of RCC electrodes were better with the increase of GO dosage. When the GO dosage was 30%， the mass specific capacitance of the RCC electrode was 129.7 F/g at the current density of 1 A/g， and the capacitance retention rate was maintained at about 96.15% after 1000 charge/discharge cycles of the test.
