The functionality of the composite has been enhanced by using polyaniline (PANI) as a Received in revised form 21 April 2014 functional component. These tunable electrically conducting biocomposites have potential applications Accepted 1 May 2014 in anti-static, electromagnetic interference shielding, sensors, electrodes, and storage devices.

Thin composite films of nanocellulose with PANI inclusions at different loadings were Keywords: manufactured using in situ polymerisation where aniline-HCl was polymerised with ammonium peroxy- A.
