Abstract: |
This invention relates to a device for preparing carbon nanotube arrays. The device comprises: a reaction chamber; a local heating device for heating the catalyst layer loaded in the reaction chamber; and a gaseous carbon supply device, fixed in the reaction chamber and above the catalyst layer, and used to supply gaseous carbon for the reaction chamber. The adoption of the local heating device and the gaseous carbon supply device can form an obvious temperature gradient at the catalyst layer, and can supply adequate carbon source for the reaction chamber. The device can realize rapid growth of carbon nanotube arryas. The method can even realize the growth of single-walled carbon nanotube arrays on the substrate. This invention also provides a method for preparing carbon nanotube arrays. |
