Fine Fabric: New, fast way to make sheets of nanotubes

Fine Fabric: New, fast way to make sheets of nanotubes: Science News Online, Aug. 20, 2005
LIGHT UP. A sheet, 16 mm by 22 mm, made of carbon nanotubes is suspended between electrodes (left). It glows (right), lighting its surroundings, when electricity passes through it.
The gossamer sheet, just 18 micrometers thick, weighs 0.4 percent as much as the same area of Mylar. Eighteen bonded nanotube sheets produced a material that is stronger than sheets of equal weight made of Mylar, of high-strength steel, or of most aluminum alloys, says Baughman.
A nanotube sheet compacts to a thickness of about 50 nanometers, or about 1/1,000th the thickness of a human hair, after it's attached to a surface, saturated with a liquid, and allowed to dry. These flexible films have been used as the glowing element of an incandescent light and as a component of electrodes for solar cells, says Baughman.
