Carbon nanotube - Wikipedia, the free encyclopedia |
 | | electric motor brushes: Conductive carbon nanotubes have been used for several years in brushes for commercial electric motors. |
 | | Nanotube composite motor brushes are better-lubricated (from the matrix), cooler-running (both from better lubrication and superior thermal conductivity), less brittle (more matrix, and fiber reinforcement), stronger and more accurately moldable (more matrix). |
 | | Since brushes are a critical failure point in electric motors, and also don't need much material, they became economical before almost any other application. |
