Abstract

Hierarchical micro/nano self‐assembled 2D structures on thin films of block copolymers/Fe hybrid materials were induced on Si/Ta substrates, either by wet chemistry or laser vacuum ultraviolet (VUV) light at 157 nm. Formation of either lamellas or micelles depends on the diblock copolymer composition and the concentration of the solutions. Honeycomb‐like nano self‐assembled structures were formed for one of the diblock copolymer based hybrid materials. The honeycomb‐like structures have a different chemical composition than the rest areas of the film and they are rich in iron. VUV irradiation is altering the surface morphology and under certain irradiating conditions semi regular micro ordering on the film surface was induced. Inside the micro‐structured domains nano‐structured semi‐regular aggregations were formed rich in iron. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract **Summary:** The study describes the investigation of the microphase‐separated morphology of a block copolymer A‐__block__‐B with the parent homopolymer A, where A is polystyrene and A‐__block__‐B is poly(perdeuterated styrene)‐__block__‐poly(methyl methacrylate) (__d__PS‐__block__‐PMMA
