  • Publication number: 20150065712
    Abstract: There is provided a method and nanocomposite for the reversible assembly of nanotubes, such as oxidized single wall carbon nanotubes, based on metal coordination. The method produces a thermally stable, neutral nanocomposite possessing enhanced mechanical, electrical, physical and chemical properties for example. Disassembly can be provided by treatment with a competing ligand compound.
