In the floating catalyst chemical vapor deposition method, the effect of the temperature distribution inside the furnace on the growth of SWCNTs was investigated. It became clear that the diameter of SWCNTs tends to increase when the low-temperature region (below 800°C) at the upstream of the electric furnace is extended. As the low-temperature region becomes longer, the time for the catalyst particle aggregation process increases, leading to an increase in the size of the catalyst particles. It was demonstrated that by controlling the temperature distribution inside the furnace, the size of the catalyst particles and the diameter of SWCNTs can be controlled.
