Bicontinuous Gyroid Copolymer Templates

The gyroid phase was first identified in diblock copolymers by two groups in 1994 [82, 83]. Following these first investigations the g5u-oid phase has been observed in AB [50, 84, 85] and ABA [86-88] block-copolymers, blends of two AB diblocks [58], and AB diblocks blended with homopolymers [52, 67] or small plasticizing molecules [89]. A comprehensive review can be found in Ref. [81]. 

Tbe fascinating bicontinuous topology of the gyroid phase makes it an irresistible target for replication in functional materials for applications in nanotechnology. While a of number porous g5U oid materials obtained from sacrificial block copolymers have been identified in bulk (Table 2.1), successful replication of g5U oid film templates has onty been rather recently achieved
