ABSTRACTThis contribution reviews the structure formation processes that are observed in binary diblock copolymer/particle and ternary diblock copolymer/particle1/particle2 mixtures. The particle core size, the polymer domain spacing as well as the particle surface chemistry are shown to determine three distinct morphological types in particle/block copolymer composites, which is the preferential layer homogeneous distribution, the interfacial segregation and center alignment of the nanocrystals within one polymer domain. The different microstructural environments of the sequestered component that are implied by the respective particle distribution result in distinctively different optical properties of the composite and have important consequences for the prospects of metal nanocrystal/block copolymer composites as a platform for photonic crystal engineering. A detailed comparison between morphological studies and theoretical predictions will be presented that aims to better understand and control morphologies of structured cluster matter and its relation to the respective optical and mechanical properties of new microstructured composite materials.
