Facile synthesis of bacterial cellulose fibres covalently intercalated with graphene oxide by one-step cross-linking for robust supercapacitors

A novel 3D cross-linked BC/GO composite featuring a tensile strength of 18.48 MPa and a conductivity of 171 S m −1 shows 160 F g −1 mass-specific capacitance and 90.3% capacitance retention after 2000 cycles in supercapacitors.
