Electrically-Conductive Sub-Micron Carbon Particles from Lignin: Elucidation of Nanostructure and Use as Filler in Cellulose Nanopapers

摘要: Carbon particles were produced from kraft lignin through carbonization of perfectly spherical, sub-micron beads obtained by aerosol flow. The structure the resulting carbon was elucidated and compared to that derived commercially available technical powder, which is undefined in geometry. In addition smaller diameters (<1 µm) those powder (100 µm), former displayed a slightly higher structural order as revealed X-ray diffraction Raman spectroscopy. With regard potential application composite structures, clearly advantageous filler cellulose nanopapers, better mechanical performance but with limited electrical conductivity. Compression sensing achieved for this nanocomposite system.
