Abstract: A carbon nanotube attached member has a substrate, which is mainly made of aluminum, and a aligned CNT film which is aligned along an alignment direction ORD. A carbon nanotube/CNT, which forms the aligned CNT film, has a length of 200 micrometers or longer. The CNT is synthesized starting from a mixed gas of acetylene, hydrogen, and argon. Furthermore, carbon dioxide is added to maintain catalyst activity. A ratio of acetylene:carbon dioxide is adjusted from 1:10 to 1:300. The aligned CNT film is partially formed. The formation range of the aligned CNT film is set by inhibiting synthesis and/or aligned growth of the CNT by a rough surface or a carbon-containing substance.

Abstract: Provided are a self-supporting film, a stacked sheet, and a method for producing a self-supporting film, the self-supporting film exhibiting low electrical resistance, low thermal resistance, and high mechanical strength, being excellent in heat resistance and flexibility, and capable of being mass-produced at low cost. A self-supporting film 1 has a porous structure consisting of aggregates 3 of metal particles 2 and voids 4. A method for producing the self-supporting film 1 includes: evaporating a metal in an inert gas of 10 Torr or more and 300 Torr or less; generating the metal particles 2 made of the metal; depositing the metal particles 2 on a substrate to form, on the substrate, a self-supporting film precursor having a porous structure consisting of the aggregates 3 of the metal particles 2 and the voids 4; and peeling the self-supporting film precursor from the substrate. A stacked sheet includes the self-supporting film 1 having a porous structure consisting of the aggregates 3 of the metal particles 2 and the voids 4, and a carrier substrate.

Abstract: Provided are a carbon nanotube production device and production method capable of realizing high-temperature heating of a catalyst raw material in a floating catalyst chemical vapor deposition (FCCVD) method, and improving the quality and yield of carbon nanotubes synthesized. A carbon nanotube production device 1 includes a synthesis furnace 2 for synthesizing carbon nanotubes; a catalyst raw material supplying nozzle 3 for supplying a catalyst raw material used to synthesize carbon nanotubes to the synthesis furnace 2; and a nozzle temperature adjusting unit 6 capable of setting a temperature of an inner portion 4 of the catalyst raw material supplying nozzle 3 higher than a temperature of a reaction field 5 of the synthesis furnace 2. By supplying to the synthesis furnace 2 the catalyst raw material that has been thermally decomposed after being heated to a temperate at which a catalyst metal will not yet be condensed, and by having the thermally decomposed catalyst raw material rapidly cooled to a CVD temperature at the synthesis furnace 2, microscopic catalyst metal particles will be generated at a high density in the space of the reaction field 5 such that carbon nanotubes having a small diameter can be vapor-grown at a high density.
