| Outline of Final Research Achievements |
The target in this study is to creatte of innovative thermoelectric conversion devices in which the thermoelectric performance of thin film is dramatically improved by making bismuth telluride nanoplates composite in the organic thermoelectric thin film. We performed to develop a technology to composite bismuth telluride nanoplates in organic thermoelectric thin films, to increase the packing density, and to make them highly oriented using electrolytic polymerization method in which nanoplates are dispersed in organic electrolytic solution. However, there was a problem in the dispersibility of the nanoplate and the organic thermoelectric thin film, and the thermoelectric performance could not be improved. Therefore, laminated thin films were prepared by changing the materials to carbon nanotubes and PEDOT. As a result, a product having 10 times or more the performance of the conventional PEDOT single electrolytic polymer film was obtained.
