Description

Although nano-scale materials, such as carbon nanotube (CNT), have high performances for industrial use, when exposed into environment, a possibility of being harmful to human body health is reported. This research pursues method to make waste CNT solidified by composition with a plastic, as the technique for fixing and confining CNT avoiding dispersion to the environment. As the first step of this research program, the synthesis of CNT from ethanol by CVD method using a high-temperature catalyst reactor was successfully conducted. Produced CNT was composed to make solidified sample with polycarbonate resin. Up to 5% CNT concentration in the resin was obtained as a result.
