  • Method for making carbon nanotube composite preform
    Patent number: 9162893
    Abstract: A method for making a carbon nanotube composite preform includes following steps. A substrate is provided. Carbon nanotubes are formed on the substrate. The carbon nanotubes and the substrate are placed in a solvent for a predetermined time. The carbon nanotubes and the substrate are drawn from the solvent. The carbon nanotubes and the substrate are dried.
    Type: Grant
    Filed: August 5, 2013
    Date of Patent: October 20, 2015
    Assignees: Tsinghua University, HON HAI PRECISION INDUSTRY CO., LTD.
    Inventors: Hai-Zhou Guo, Feng-Wei Dai, Yuan Yao, Chang-Shen Chang, Chang-Hong Liu, Kai-Li Jiang

  • Carbon nanotube composite preform and method for making the same
    Patent number: 8530052
    Abstract: A carbon nanotube composite preform includes a substrate and a plurality of carbon nanotubes formed thereon. Each carbon nanotube includes a first end adjacent to the substrate and a second end away from the substrate. Gaps between the second ends of the carbon nanotubes are bigger than gaps between the first ends thereof. The method for making the carbon nanotube composite preform includes the following steps: (a) providing a substrate; (b) forming a plurality of carbon nanotubes (e.g., a carbon nanotube array) on the substrate; (c) placing the carbon nanotubes and the substrate in a solvent for some time; (d) removing the carbon nanotubes and the substrate from the solvent; (e) drying the carbon nanotubes and the substrate to form a carbon nanotube composite preform.
