Abstract: |
The present invention relates to a carbon nano tube. Said carbon nano tube includes firest carbon nano tube portion and second carbon nano tube portion which are formed from single isotopic substance, and said first carbon nano tube portion and second carbon nano tube portion are alternatively arranged along the longitudinal direction of the carbon nano tube. Its preparation method includes improved chemical gas deposition process, electric arc discharge process and laser ablation process. Said invention also provides the equipment for implementing above-mentioned preparation method. |
