Synthesis and characterisation of nanocellulose-based polyaniline conducting films

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