Abstract
A flexible, electrically conductive and low-cost composite sheet has been prepared combining multi-walled carbon nanotubes (MWCNTs) and cellulose pulp using simple solution mixing method. The uniform attachment of MWCNTs on to the cellulose fibres of the composites lead to a gradual decline of the sheet resistance with an enhanced electrical conductivity. The crystallinity of the composites is also found to be increased. The composites remain thermally stable up to 550 K as well as demonstrate improved flame retardancy. The conducting CNT networks of the composites are not disrupted even after 600 bending cycles, indicating almost no loss of conductivity. This conducting and flexible composite sheet can be used in different energy storage devices.
