Ionic liquid coated single-walled carbon nanotube buckypaper as supercapacitor electrode

- Single walled carbon nanotubes (SWCNTs) were debundled by ionic liquids.
- ILs-coated SWCNT buckypaper had low surface resistance and high packing density.
- ILs-coated SWCNT buckypaper used as electrode exhibited excellent capacitance performance.
