METHOD OF COUPLING AND ALIGNING CARBON NANOTUBES IN A NONWOVEN SHEET AND ALIGNED SHEET FORMED THEREFROM |
| 摘要 |
Carbon nanotubes are coupled and aligned in a non-woven sheet as measured by failure strain by drawing the sheet with a coupling agent such as triphenylmethane and preferable a liquid diluent such as chlorosulfonic acid or sulfuric acid. The formed non-woven sheet has a full width at half maximum as determined by wide angle X-ray diffraction of not greater than 20°. |

1. A method aligning carbon nanotubes in a non-woven sheet comprising the steps of:
(a) providing a non-woven sheet of carbon nanotubes with nanotubes which are not aligned, (b) contacting the non-woven sheet of carbon nanotubes with a coupling agent to achieve mechanical coupling between adjacent carbon nanotubes. (c) drawing the non-woven sheet of carbon nanotubes with mechanically coupled carbon nanotubes to impart:
(i) stress among carbon nanotubes and(ii) alignment of individual nanotubes in a direction the non-woven sheet is drawn. |
