Abstract
Apparatus to produce carbon nanotubes (CNTs) of arbitrary length using a chemical vapor deposition (CVD) process reactor furnace is described, where the CNTs are grown axially along a portion of the length of the furnace. The apparatus includes a spindle and a mechanism for rotating the spindle. The spindle located within a constant temperature region of the furnace and operable to collect the CNT around the rotating spindle as the CNT is grown within the furnace.
Claims14
Apparatus to produce carbon nanotubes (CNTs) of arbitrary length using a chemical vapor deposition (CVD) process reactor furnace, the CNTs grown axially along a portion of the length of the furnace, said apparatus comprising:
- a spindle;
- and
- a mechanism for rotating said spindle, said spindle located within a constant temperature region of the furnace and operable to collect the CNT around the rotating said spindle as the CNT is grown within the furnace.
11-18. (canceled)
A chemical vapor deposition (CVD) process furnace comprising:
- a reaction chamber configured for the growth of carbon nanotubes from a catalyst therein and a gas flow therethrough;
- and
- a rotatable spindle disposed within said reaction chamber, said rotatable spindle downstream from the catalyst with respect to the gas flow, said rotatable spindle operable for collecting the CNTs around said rotatable spindle as the CNTs are blown in the direction of said rotatable spindle due to the gas flow.
