Abstract

original image

3D periodic ordered metallic-nanostructure-based hybrid materials with alignment on the micrometer scale are fabricated. Self-assembly of diblock copolymers, combined with inorganic components synthesized in situ, guides the inorganic materials into local polydomain nanostructures. Subsequently, through application of external mechanical shear, the spatial arrangement and periodicity of the nanostructures is extended into macroscopically ordered domains.
