Research Abstract

Combustion synthesis of carbon nanotube (CNT), in which thermal plasma is coexist with heat and carbon sources, is expected to make the mass production of CNT with low cost possible. It has been found that the CNT growth in this method is promoted by applying the direct current electric field. In this study, the effect of electric field on the change in temperature, concentration of chemical species of the CNT formation field, the amount and characteristics of the CNT formed are investigated. The effect of electric field on the CNT growth in the electric furnace is also investigated. As a result, the promotion of CNT growth and improvement of crystallization of CNT are observed in the combustion synthesis. It is suggested that the effect of electric field on the CNT manufacturing in the combustion synthesis can be ascribed to the increase in collection of CNT formed due to the motion of thermal plasma and the promotion of catalytic activity.
