Problems solved by technology

[0007] Compared with the prior art, the present invention has the following beneficial effects: utilizing the physical and chemical inertness of the carbon nanotubes itself, which does not react with other materials, it not only enables the carbon nanotubes to be used on the metal coating with the metal coating treatment agent When it is used, it can be dispersed evenly, and the surface of the carbon nanotube structure can be fully coated with metal, which solves the problem of uneven distribution of the coating in the past. Even when it is used in a field emission display, it can improve the carbon nanotube itself under the action of an electric field. A large field enhancement factor makes it easier for the electron beam to be released and increases the current density of the emission

Abstract

The invention discloses a metal plating method for carbon nanotubes. Mainly, the method adopts low-carbon-number alcohol solvents and surfactants having a functional group of thioalcohol or sulfonic acid and uses ultrasonic vibration to fully disperse the carbon nanotubes in electroless plating surface to completely coat a plating layer on the surfaces of the carbon nanotubes, thereby solving the problem of uneven plating layer distribution caused by the aggregation of carbon nanotubes in the prior art.

Description

【Technical field】 [0001] The invention relates to carbon nanotubes, in particular to a method for metal coating on carbon nanotubes by using a metal coating treatment agent. 【Background technique】 [0002] Carbon Nanotube (CNT) was accidentally discovered by Professor Sumio Iijima, a senior researcher at NEC in Japan, when C60 was prepared by arc discharge method in 1991, when he observed carbon clusters with a transmission electron microscope. According to different growth methods, the types of carbon nanotubes are generally divided into single-layer carbon nanotubes with a diameter of several nanometers, and multi-layer carbon nanotubes with a diameter of tens of nanometers. nanometers. Depending on the arrangement of carbon atoms in carbon nanotubes, carbon nanotubes with semiconductor or conductor properties can be obtained, which makes it not only applicable to field emission displays, but also to hydrogen storage materials, biomedicine, transistors, etc. Among variou...
