Chementator: Carbon nanotubes

By Chemical Engineering |

CEVP Ltd. (Newhaven, U.K.; edlinks.chemengonline.com/5825-544) has developed a fabrication tool that grows carbon nanotubes (CNTs) at room temperature by a process developed by the University of Surrey’s Advanced Technology Institute (ATI; U.K.; edlinks.chemengonline.com/5825-545). The NanoGrowth tool is undergoing trials at ATI, and the two partners plan to commercialize the technology in March. NanoGrowth is designed to achieve nanomaterial growth across areas up to three inches in diameter by a plasma-enhanced, chemical-vapor deposition and vacuum process. The system is optimized for the growth of CNTs with controlled properties, such as density, length and position. A thermal-control system keeps the substrate at room temperature, which allows CNTs to be grown vertically and horizontally, even on heat-sensitive material, such as plastic or metallized paper, says CEVP. The tool may also be used to grow other nanomaterials, such as nanowires of doped silicon and tungsten oxide.   Click here for a full pdf version of the Chementator Section
