    Ex-MWNTs: Graphene Sheets and Ribbons Produced by Lithium .

    We found that multiwalled carbon nanotubes (MWNTs) can be opened longitudinally by intercalation of lithium and ammonia followed by exfoliation. Intercalation of open-ended tubes and exfoliation with acid treatment and abrupt heating provided the best results. The resulting material consists of: (i) multilayered flat graphitic structures (nanoribbons), (ii) partially open MWNTs, and (iii .

    Carbon nanotube - Wikipedia

    Structure of single-walled tubes . The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the positions of the carbon atoms. Since the length of the carbon-carbon bonds is fairly fixed, there are constraints on the diameter of the cylinder and the arrangement of the atoms on it.

    Reinforced Thermoplastic Natural Rubber (TPNR) Composites .

    As the MWNTs content in the TPNR increases, the stress level gradually increases but at the same time the strain of the nanocomposites decreased. This is because the MWNTs included in the TPNR matrix behave like physical crosslinking points and restrict the movement of polymer chains (Sang et al., 2007). This shows that the inclusion of MWNTs .

    Multi-Walled Carbon Nanotubes: Production, Analysis, and .

    Multi-walled carbon nanotubes (MWNTs) and single-walled carbon nanotubes (SWNTs) are similar in some aspects, yet are known to have notable differences.
