Synthesis and structure analysis of continuous long CNT by nanostructure control in reaction field

碳纳米管具有特殊的纳米结构和性质。本研究的目的是利用催化化学气相沉积（CCVD）方法，在反应区域内通过纳米结构的精确控制，获得长碳纳米管并改善其性能。为了达到这一目的，我们采用了新的方法（碳源供应区和碳纳米管生长区分开）和改进的常规方法来研究碳纳米管的合成。因此，我已经实现了高质量的碳纳米管的长碳纳米管，也通过优化使用CCVD方法的生长条件，控制精确的生长控制的碳纳米管的高导电性。

Carbon nanotubes (CNTs) have extraordinary nanostructure and properties. Purpose of this research is achievement of the long CNTs and their improving properties by nanostructure precise control in reaction field using catalytic chemical vapor deposition (CCVD) method. To achieve the purpose, the CNT synthesis was investigated using new method (separating of carbon source supply zone and the CNTs growth zone) and also modified conventional method. As a result, I have achieved the long CNTs of high quality CNTs and, also high electrical conductivity of the CNTs by optimizing the growth conditions using the CCVD method, controlling precise growth control.
