CARBON NANOTUBE - POLYSACCHARIDE COMPOSITE

摘要

The present invention provides methods for the fabrication CNT dispersions using polysaccharides, especially hemicelluloses, and most advantageously xylan.;The present invention also provides methods to isolate, and purify hemicelluloses from plant materials.;The present invention provides methods and compositions for the coating of solid surfaces using CNT dispersions.;One currently preferred method coating of a surface is electrospraying the CNT dispersion.;The present invention provides electrically conducting materials that can replace conducting plastics, graphite, and even some metals as electrical conductors.;In one embodiment the present materials can be used as stealth coatings.;In another embodiment the present materials can provide shield against high frequency electromagnetic radiation, while being permeable to low frequency magnetic field.;In one specific application the dispersion fabricated from double walled carbon nanotubes (DWNTs), and xylan can be used to fabricate transparent electrically conducting films.;In one embodiment of the present invention the surface films will be cross-linked, and these films can be used in multiple applications including supercapacitors.
