Outline of Final Research Achievements

In recent years, thermoelectric conversion of heat in the environment is considered promising for generating electric power. In this purpose, carbon nanotube CNT is extensively studied because of their lightweight and highly flexibility. In this research, we tried to generate n-type CNT which is necessary for high-efficiency power generation by photo-chemical methods. Stable n - type thermoelectric power generation characteristics were observed in the CNT composite membrane prepared by immersing CNT film in aqueous solution of aromatic amines. We also used a hydride-type amine as a reducing agent, it was possible to obtain an effective n - type CNT.
