| Research Abstract |
Three-phase gyroid structures were formed by a poly(isoprene-b-styrene-b-2-vinylpyridine)(ISP) and a poly(4-hydroxy styrene)(H), and nanoporous network structures were created by treating the sample film in acetic acid. Iron chloride(III) was incorporated into the phase-separated structures of poly(styrene-b-4-vinylpyridine)(S4P) diblock copolymers followed by forming a nanoporous cylindrical structure by simply immersing the ultrathin sections of the sample in water. Surface-modified semiconductor nanoparticles were introduced in periodic structures of the other S4VPs. Furthermore, gold nanoparticles were periodically placed at the interface of a poly(styrene-b-isoprene) diblock copolymer by grafting two polymer species on gold nanoparticle surface using chemical bonds.
