  • Patent number: 9187823
    Abstract: A method of growing carbon nanostructures on a conductive substrate without the need for a vacuum or low-pressure environment provides high electrical field strengths to generate the necessary carbon ions from a feedstock gas and to promote alignment and separation of the resulting structures. In one embodiment, substantially uniform “vertical” nanostructures may be formed around the periphery of an extended wire for use in corona discharge applications or the like. Growth on a planar substrate may provide use with a variety of apparatus requiring a high specific surface conductor such as capacitors, batteries, and solar cells.
    Type: Grant
