CARBON NANOTUBE ASSEMBLY, METHOD FOR PRODUCING THE SAME, AND CARBON NANOTUBE TWISTED YARN

摘要

PROBLEM TO BE SOLVED: To provide a carbon nanotube assembly from which a carbon nanotube twisted yarn having excellent electrical properties and mechanical properties is produced.SOLUTION: The carbon nanotube assembly is obtained by chemical vapor deposition on a substrate and characterized in that a part of at least 80% in the height has a linearity of ≤10°, the surface smoothness is ≤0.3 μm, and the bulk density is ≥30 mg/cm.
