项目摘要

In this work, we carried out to research to produce and purify good quality single wall carbon nanatubes. The main objective of this work was to control the arc plasma using the magnetic field and synthesis nanotubes with controlled morphology. Furthermore, the SWNTs synthesized were purified using hydrothermal treatment, which was already developed by us. Final aim of this research was to develop a comprehensive methodology for the production of highly pure (above 99%) single wall SWNTs in large quantities.In the year 2000, SWNTs synthesis conditions were optimized in the arc-discharge chamber designed and manufactured in the year 1999, and evaluated the quality and condition of purified SWNTs using transmission electron microscope, Raman spectroscopy and X-ray diffractometer, etc.. Furthermore, a modified version of the arc-discharge chamber was designed and manufactured to enable experiments under strong magnetic fields (max. 5 Tesla). As a consequence, information related to the growth mechanism of tubes was acquired. And also, SWNTs were synthesized in a magnetic field as strong as five tesla for the first time.Based on the above research findings, we succeeded in the synthesis and purification of SWNTs and supply quality SWNTs to other groups. As a result, we contributed to the property evaluation and application oriented research fields of this special research project.

本工作对制备和纯化高质量的单壁碳纳米管进行了研究。本论文的主要目的是利用磁场控制电弧等离子体，并合成形貌可控的纳米管。此外，利用我们已经开发的水热处理方法对合成的单壁碳纳米管进行了纯化。本研究的最终目的是开发一种用于生产高纯度2000年，在1999年设计制造的电弧放电室中优化了单壁碳纳米管的合成条件，并利用透射电镜、拉曼光谱和X射线衍射仪对纯化后的单壁碳纳米管的质量和状态进行了评价，等等.此外，还设计和制造了一个改进版的电弧放电室，以便在强磁场（最大）下进行实验。5特斯拉）。结果，获得了与管的生长机制相关的信息。基于以上的研究成果，我们成功地合成和纯化了单壁碳纳米管，并为其他研究小组提供了高质量的单壁碳纳米管。因此，我们为这个特别研究项目的属性评估和应用导向的研究领域做出了贡献。
