Method for manufacturing mono-layer carbon nano pipe

Abstract

This invention provides a method for manufacturing the same length, high purity, single-layer carbon nanometer tubes with safety, high yield and controllable product length. The carbon series material, including single-layer carbon nanometer tubes, manufactured by various kinds of synthesis, is treated by nitric acid or the like, removing the metal impurities and forming defects on the wall of said nanometer tubes. Then, said carbon series material is treated by nitric acid, hydrogen peroxide, persulphates or this kinds of oxidants, cutting said single-layer nanometer tubes, finally the same is treated by reductive gas, such as ammonia, for removing the carbon impurity, and restoring from the defects for the single-layer carbon nanometer tubes.

Description

technical field

[0001] The present invention relates to a manufacturing method of single-walled carbon nanotubes, a manufacturing method of single-walled carbon nanotubes and a device for applying single-walled carbon nanotubes, for example, preferably applied to the manufacture of electronic components using single-walled carbon nanotubes. Background technique

[0002] Recently, carbon nanotubes have attracted the attention of many researchers. Among them, the research and development of single-walled carbon nanotubes are particularly expected due to their unique one-dimensional structure and unusual structure-dependent properties. Single-walled carbon nanotubes potentially exhibit superior mechanical properties to any other known material due to their seamless cylindrical graphite-like shell structure. In addition to these excellent mechanical properties, single-walled carbon nanotubes exhibit a variety of unique chemical and physical properties that provide possible appl...
