| Research Abstract |
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.
