US Patent 7744793 - Growing nanotube forrests

This patent teaches a method of bulk carbon nanotube production which reduces impurities and grows a nanotube forest. Claim 1 reads:

1. A method for producing a nanotube film, the method comprising:

supplying a carbon-bearing precursor gas and using the carbon-bearing precursor gas for growing a first nanotube forest on a first substrate positioned within a reaction chamber having an access port, wherein the reaction chamber is positioned in a furnace; and

pulling a first length of nanotube film from the first nanotube forest on the first substrate through the access port while the nanotube forest is in the reaction chamber.
