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

通过聚（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）形成三相螺旋结构，并通过在乙酸中处理样品膜来产生纳米多孔网络结构。氯化铁（III）被纳入相分离的聚（苯乙烯-b-4-乙烯基吡啶）（S4 P）二嵌段共聚物的结构，然后通过简单地将样品的水溶性部分浸入水中形成纳米多孔圆柱形结构。在其他S4 VP的周期性结构中引入了表面改性的半导体纳米颗粒。此外，金纳米粒子周期性地放置在界面的聚（苯乙烯-b-异戊二烯）二嵌段共聚物通过接枝两种聚合物物种的金纳米粒子表面上使用化学键。

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.
