US Patent 7771784 - CNT thin film production

This patent from Materials and Eletrochemical Research (MER) teaches a method to form carbon nanotube films on arbitrary surfaces with improved efficiency. Claim 1 reads:

1. A method for directly forming a thin film of nanotubes from a flowing aerosol suspension of nanotube particles produced as the exhaust flow from a nanotube-producing reactor, which comprises:

depositing said nanotube particles from said flowing aerosol suspension onto a filter substrate; and

adhering the as-deposited nanotube particles to a second substrate.
