| Outline of Final Research Achievements |
Aiming to contribute to fundamental technologies for device fabrication of single-walled carbon nanotubes (SWCNTs), we have developed the advancement of SWCNT dispersants that can adsorb and desorb by photostimulation and thin film processing technology. We have used a method of controlling the surface properties of SWCNT, which is easy to agglomerate due to the strong molecular interaction and which is difficult to handle in solution process. We have tuned the surface properties of SWCNT by adsorption-desorption behavior of a dispersant which changes its structure by photoreaction. We have investigated a novel photoresponsive dispersant by optimized their structures and solved the problems of conventional dispersants (surfactants, etc.) and optimized the structure. We have studied a novel processing technology of SWCNT thin films using the optimized photofunctional dispersant and accumulated basic knowledge for applied research on electrodes and thin film transistors using SWCNTs.
