摘要	In this paper, a relatively new concept of using nanocellulose as matrix material in a composite system has been explored. The functionality of the composite has been enhanced by using polyaniline (PANI) as a functional component. These tunable electrically conducting biocomposites have potential applications in anti-static, electromagnetic interference shielding, sensors, electrodes, and storage devices. Nanocellulose was extracted by hydrolysing bleached flax yarn with sulphuric acid (60 wt.%) at 55 degrees C for 1 h under vigorous stirring. Thin composite films of nanocellulose with PANI inclusions at different loadings were manufactured using in situ polymerisation where aniline-HCl was polymerised with ammonium peroxydisulfate (APS) as oxidant in aqueous nanocellulose suspension. Thin composite films showed improved combination of flexibility and conductivity. These films could be bent by 180 degrees without breaking. The dependence of electrical conductivity on the concentration of polyaniline (0, 10, 20, 30 wt.%), was investigated. It was found that the conductivity of a film increased significantly with the increase in PANI content from 10% to 30%. The conductivity of the nanocomposite containing 30 wt.% reached 1.9 x 10(-2) S/cm, which shows promise in the application of paper-based sensors, flexible electrode and conducting adhesives. The composite film showed improved thermal stability above 300 degrees C by 15% less weight loss at 500 degrees C compared to pure nanocellulose films. The morphologies, microstructures, thermal stability properties of the nanocomposite films were also investigated. (C) 2014 Elsevier Ltd. All rights reserved.
