| Outline of Final Research Achievements |
Very fine nanostructure with domain periodicity less than 20 nm, which was difficult to fabricate from a diblock copolymer composed of two hydrophobic blocks, was achieved from a super-strongly segregated block copolymer. A superhydrophobic block and a hydrophilic block (specifically, poly(pentafluorostyrene) and poly(acrylic acid)), which were different in terms of elemental composition, were used as a component pair for a block copolymer. Such component pair serves as a super-strongly segregated system; therefore, the block copolymers even with small degrees of polymerization (for example, about 40) represented nanophase-separated structures. In fact, one of such block copolymers attained very fine nanostructure with domain periodicity less than 10 nm.
