Outline of Final Research Achievements

Unlike homopolymer blend systems that macroscopically phase-separate, block copolymers, in which different species of polymers are connected by covalent bonds, phase-separate into periodic structures, i.e., microdomain structures, on the order of its molecular size because of the connectivity. Microdomain structures form a variety of morphologies, such as lamellae, cylinders, spheres, etc; Here, an ordered bicontinuous double gyroid (OBDG) structure, one of the three-dimensional network structure, was used as a host to fabricate a nanowire.
In addition, the OBDG structure and its order-order transition into an ordered bicontinuous double diamond structure was investigated in detail by small-angle X-ray scattering.
