    摘要: The invention relates to a process for sorting and separating a mixture of (n, m) type single-wall carbon nanotubes according to (n, m) type. A mixture of (n, m) type single-wall carbon nanotubes is suspended such that the single-wall carbon nanotubes are individually dispersed. The nanotube suspension can be done in a surfactant-water solution and the surfactant surrounding the nanotubes keeps the nanotube isolated and from aggregating with other nanotubes. The nanotube suspension is acidified to protonate a fraction of the nanotubes. An electric field is applied and the protonated nanotubes migrate in the electric fields at different rates dependent on their (n, m) type. Fractions of nanotubes are collected at different fractionation times. The process of protonation, applying an electric field, and fractionation is repeated at increasingly higher pH to separated the (n, m) nanotube mixture into individual (n, m) nanotube fractions. The separation enables new electronic devices requiring selected (n, m) nanotube types.

    摘要: Buckyrock is a three-dimensional, solid block material comprising an entangled network of single-wall carbon nanotubes (SWNT), wherein the block comprises greater than 75 wt % SWNT. SWNT buckyrock is mechanically strong, tough and impact resistant. The single-wall carbon nanotubes in buckyrock form are present in a random network of individual single-wall carbon nanotubes, SWNT “ropes” and combinations thereof. The random network of the SWNT or SWNT ropes can be held in place by non-covalent “cross-links” between the nanotubes at nanotube contact points. In one embodiment, SWNT buckyrock is made by forming a SWNT-water slurry, slowly removing water from the slurry which results in a SWNT-water paste, and allowing the paste to dry very slowly, such that the SWNT network of the SWNT-water paste is preserved during solvent evaporation. Buckyrock can be used in applications, such as ballistic protection systems, involving light-weight material with mechanical strength, toughness and impact resistance.
