摘要：Considering the high requirements for robust and flexible power supplies, the green and sustainable fiber-based supercapacitor is suitable to accommodate the inevitable serious deformation and low radiation issues in wearable electronic energy storage devices due to its easy integration. Compatible natural nanocellulose (NFC) as a framework and the two-dimensional conductive graphene (GO) nanosheets constructed a dense brick-and- mortar structure, which the dispersing effect of NFC avoided GO aggregation. The utilization of the green- reducing agent and the obtained NFC/reduced graphene oxide (rGO) composite film endowed the composite film with a continuous conductive network by the self-assembly behavior of NFC and GO, that the lightweight flexible electrode NFC/50rGO with 13 mu m thickness had high conductivity (883.70 S m- 1), a total electromagnetic shielding efficiency of 27.1 dB at 8.2 GHz frequency, electrochemical behavior (mass-specific capacitance up to 170.6F g- 1), and reversible charge-discharge behavior. Developing a green and portable small electronic device with such a flexible and high-strength electrode symbolizes the critical development direction in the future electronic equipment field.
