Large Sheets of Carbon Nanotubes Produced

Ever since scientists first figured out how to make carbon nanotubes-tiny cylinders of carbon with diameters of a few tens of nanometers-they’ve been touted as the material of the future: as strong as steel but far lighter, with the ability to conduct electricity in useful ways. The problem is that because they’re so small, it’s been difficult to make them at scales that would be useful to industry. You can’t really build a lightweight airplane a few microns at a time, after all.

Now a New Hampshire company, Nanocomp Technologies of Concord, says it has overcome that limitation, producing sheets of carbon nanotubes that measure three feet by six feet and promising slabs 100 square feet in area as soon as this summer.
