US Patent 8204407 - CNT corona wires
http://www.freepatentsonline.com/8204407.html
Corona wires are important components of electrophotographic laser printers used for creating electric charge on a photosensitive drum. This patent from Xerox teaches how carbon nanotubes can produce corona wires with improved durability. Claim 1 reads:
1. A charging device comprising:
a receptor; and
a wire coronode disposed opposing and spaced apart from the receptor,
wherein the wire coronode comprises one or more carbon nanotube yarns arranged to emit a corona charge to the receptor using a low operating voltage, and each of the one or more carbon nanotube yarns has a minor dimension of about 100 microns or less and a resistivity of about 4×10−4 Ω-cm or less.
