摘要： Provided is a carbon nanotube aggregate by which it is possible to realize further reduction in resistance compared to conventional carbon nanotube wires, as well as realizing comparable resistivity to copper and aluminum, and major improvement in electrical properties.
A CNT aggregate (1) is constituted of a plurality of CNT bundles (11) having a structure with one or more walls. The CNT bundles 11 are bundles having a plurality of CNTs (11a). In the CNT aggregate (11), the ratio of the total number of CNTs having a two- or three-walled structure in relation to the number of CNTs (11a) is 75% or greater, and among peaks due to a G band of a Raman spectrum in Raman spectroscopy, a G+/Gtotal ratio due to semiconductor CNTs is 0.70 or greater.-

摘要： To provide a coreless motor that includes a carbon nanotube electric wire with an excellent shape retention property as coil windings and excellent heat dissipation characteristics as coil windings. The coreless motor includes a rotating shaft, a rotor plate attached to the rotating shaft, and a coil supported by the rotor plate. The coil includes a carbon nanotube electric wire, the carbon nanotube electric wire including a carbon nanotube wire and a coating layer, the carbon nanotube wire including a plurality of carbon nanotubes, the coating layer including an insulating layer that covers the carbon nanotube wire so as to insulate the carbon nanotube wire. The carbon nanotube electric wire is such that when portions of 1 cm from opposite ends of each of carbon nanotube electric wires with a length of 12 cm are pinched with jigs, and each of the carbon nanotube electric wires is held in a horizontal state with a tension of 100 gf for 10 minutes, and then only the jig at one end of each of the carbon nanotube electric wires is removed, the proportion of carbon nanotube electric wires that drop at the one end by 1 cm or more relative to another end on the opposite side is less than or equal to 20%.

摘要： There is provided a CNT wire capable of materializing a low resistivity and improving the electroconductivity. The CNT wire (1) is formed from a single CNT aggregate (11) constituted of a plurality of CNTs (11a), (11a) ··· having a single- or multi-walled structure, or formed by bundling a plurality of the CNT aggregates (11). The proportion of the total number of the CNTs having a double-walled or triple-walled structure based on the number of the plurality of CNTs (11a), (11a) ··· constituting the CNT wire (1) is 75% or higher; the proportion of the total number of the CNTs having an average diameter of the innermost wall of 1.7 nm or smaller based on the number of the CNTs constituting the CNT wire (1) is 75% or higher; and the full-width at half maximum Δθ in azimuth angle in azimuth intensity distribution by SAXS indicating orientation of the plurality of CNT aggregates (11), (11) ··· is 60° or smaller.
