US Patent 7666051 - Field emission cloth using nanostructures

Carbon nanomaterials have been proposed to create electron emission devices by companies including Applied Nanotech, Canon, and Samsung. This patent from Boston College teaches a way to of growing such nanomaterials directly from a carbon cloth achieving emission current densities of 1mA/cm2 at a field of 0.4V/micron. Claim 13 reads:

13. A device capable of delivering an enhanced field emission current density at a low electric field comprising:

a conductive cloth substrate woven of fiber bundles oriented in at least two directions, wherein the conductive cloth substrate has a rough finish; and

a plurality of nanostructures grown on the conductive cloth substrate.
