Carbon nanotubes/kraft lignin composite: Characterization and charge storage properties

- Nanocomposite consisting of multi-walled carbon nanotubes and kraft lignin was prepared and characterized.
- The characterization confirmed uniform, dense packing of the biopolymer on the surface of the nanotubes.
- The nanocomposite can effectively store electric charge on the basis of the double layer capacitance and red-ox reactions.
