Abstract：Carbon nanotubes (CNT) material due to its excellent optical, electrical, magnetic, thermal, mechanical properties and processing performance, which has aroused great concern of science and technology workers, is expected to have wide application prospect in the field of optoelectronic components, high performance materials etc.. On the other hand, the aligned or ordered arrangement of carbon nanotubes (CNTS) makes their composites with a lot of new mechanical, electrical and optical properties, and will greatly promote the application and development of CNT materials. Therefore, it is of great significance to realize the uniform dispersion and orderly arrangement of CNTS and to promote the application of CNTS in electronic devices. In this thesis, the order of carbon nanotubes has been studied:

The design and fabrication of MASK tubes, the preparation of electrodes, the dispersion and processing of CNTS (carbon nanotubes), and the study of the ordering of CNTS (carbon nanotubes).

This paper intends to deal with the impurities of carbon nanotubes by acid and alkali solution, through effective dispersant on dispersion of carbon nanotubes in solution, and then use the different voltage of ordered carbon nanotubes on the electrode.The first part mainly on the CNTS (carbon nanotube) concept is introduced in detail, through the analysis of CNTS (carbon nanotube) history and technical characteristics of the development of in-depth study of the CNTS (carbon nanotubes) the development direction and development prospects. The preparation technology, advantages and disadvantages of CNTS (carbon nanotubes) are briefly introduced.The second part mainly introduces the tube electrode for the detection of CNTS using MASK (carbon nanotube) conductivity in the variables under the influence of the carbon nanotube is dispersed by dispersing process of single-walled carbon nanotubes.In the third part of this paper, the conductivity and order of CNTS (carbon nanotube) are discussed by adopting the control variable method.

Keywords: CNTS (carbon nanotube); ordering; dispersion processing; scanning electron microscopy (SEM)
