High Purity Carbon Nanotube, Process For Preparing The Same And Transparent Conductive Film Using The Same
Abstract:
ProblemTo provide a process for producing single-walled carbon nanotubes with which highly pure, high-quality single-walled carbon nanotubes can be produced with high efficiency, and to provide a transparent conductive film using the single-walled carbon nanotubes obtained by that production method.SolutionA process for producing single-walled carbon nanotubes by chemical vapor deposition (CVD), wherein particles of a nonmetallic material containing 500 ppm or lower of metallic impurities including metals and compounds thereof are used as growth nuclei; and after a growth gas is introduced into a furnace used for growing carbon nanotubes, the growth gas used in an initial stage of growth of carbon nanotubes and the growth gas used in a stage of growth of regular carbon nanotubes (stationary growth stage) thereafter are prepared to different compositions and different partial pressures.
