Gyroid network structures from ABC block terpolymers and the related nanoporous/hybrid materials

由聚（异戊二烯-b-苯乙烯-b-2-乙烯基吡啶）（ISP）和聚（4-羟基苯乙烯）(H)形成三相旋回结构，并通过乙酸处理样品膜形成纳米孔网络结构。将氯化铁（III）加入到聚（苯乙烯-b-4-乙烯吡啶）（S4P）二嵌段共聚物的相分离结构中，然后将样品的超薄切片简单地浸入水中形成纳米多孔圆柱形结构。在其他s4vp的周期结构中引入了表面修饰的半导体纳米粒子。此外，通过在金纳米颗粒表面用化学键接枝两种聚合物，将金纳米颗粒周期性地置于聚苯乙烯-b-异戊二烯二嵌段共聚物的界面上。

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.
