Effect of Electron Beam Irradiation on Electrochemical Properties of CNT

In order to improve the physical properties of Carbon nanotubes(CNTs) by removing the amorphous carbon and metal impurities by increasing the purity of CNTs, a liquid phase purification method and a vapor phase purification method after heat treatment have been studied. To solve this complicated process, other researches are proceeding on the change of properties of CNTs through various light sources such as ultrasonic treatment and microwave. In this study, amorphous carbon in CNTs was removed by electron beam irradiation and the improvement of electrochemical properties of CNTs were proceeded. This paper researched the change of electrochemical properties of CNTs through electron beam irradiation for purifying impurities. After a Raman analysis, to study the impact of the electron beam irradiation by the electrical conductivity of the CNTs was to determine the aimed air chemical structure change that the inflection point appearing in 1,000 kGy. It can be seen that by reducing the proportion of the amorphous carbon electrical conductivity is improved.
