US Patent 7504078 - CNT alignment conveyor

This patent from the University of Kentucky teaches a fabrication method of aligned films of carbon nanotubes on a substrate providing potential for mass production of CNT electronics. Claim 1 reads:

1. An apparatus for continuous production of aligned carbon nanotubes, comprising:

a reactor defining a hollow interior;

a conveyor for continuously passing a substrate through the hollow interior of the reactor at a predetermined rate of travel; and

an injector for delivering a hydrocarbon feed solution dispersed in an inert carrier gas into the hollow interior of the reactor;

whereby aligned carbon nanotubes are formed on the substrate.
