| Outline of Final Research Achievements |
An ABC triblock terpolymer was found to self-assemble an interesting "double helical structure": The middle block (B) formed helical microdomains around hexagonally-packed A core-cylinders.Using this intriguing nano-structure, we aimed to develop a new class of hybrid material in which the helical microdomains were transformed to metal phases by selectively introducing metal nano-particles into helical phases. Control of helical handedness of the B helical microdomains in the double helical structure was also essential for generating a hybrid material with prominent functionality.
We found a way to selectively introduce metal nano-particles into helicxal microdomains, if their diameter is about 1/4 of those of the helical microdomains. Helical handedness was found to be uniform (left-handed) when the double helical structures were perpendicularly aligned with respect to the substrate in the terpolymer thin film.
