Abstract

The invention belongs to the technical field of the nanometer material preparation, particularly related to the preparation method of a carbon nano-tube (CNT), comprising the following steps: dissolve the complex block ferrocene of 0.002g / mL to 0.04g / mL into the xylene; put the solution into the quartz weighing bottle and put the weighing bottle into the hydrothermal reactor; put the reactor into a box resistor-stove to be heated to 600 DEG C to 800 DEG C for 12 to 18 minutes to get black product, which is carbon nano-tube (CNT). The preparation method of the carbon nano-tube (CNT) has the advantages of simple technology, easy operation in the whole preparation process, easy controlling condition and convenient post treatment, thus applicable to mass production. The material of the preparation method of the carbon nano-tube (CNT) is easy to get, without need of any special addition agent or catalyst, thus characterized in economic and low cost. The preparation method of the carbon nano-tube (CNT) does not produce by-product which pollutes the environment during preparation, meeting the demand of sustainable development, thus being an environment-friendly synthesis craft.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a method for preparing carbon nanotubes. Background technique [0002] Since 1991, Japanese electron microscope scientist Iijima Sumio (S.Iijima) prepared C by arc method. 60 Since carbon nanotubes were first discovered in the process of carbon nanotubes, due to their unique structure and physical and chemical properties such as high strength, high specific surface area, heat resistance, and excellent electron conductivity, these properties make carbon nanotubes in mechanical, micro Electronics, optics, materials science and chemistry and biological sciences have shown broad application prospects, attracted great attention from many scientists in the fields of chemistry, physics, electronics, materials, etc., and become the research frontier and hot spot in the field of international new materials . [0003] At present, the research on the character...
