Highly ordered nanostructured surfaces obtained with silica-filled diblock-copolymer micelles as templates.
In this work, we present the size-controlled preparation of silica-filled micelle cores and their self-assembly behavior, which is dependent on the block lengths, different coating techniques, and substrates. Furthermore, we present a way to use these structures as templates for highly ordered magnetic nanostructures, revealed by Ar-ion milling. The resulting structures were characterized by different imaging and scattering techniques and model simulations were performed. The characterization of the obtained nanostructured surfaces has be performed with atomic force microscopy, by scanning electron microscopy, grazing-incidence X-ray small-angle scattering, and X-ray reflectivity measurements. The magneto-optical Kerr effect was utilized to investigate magnetic properties.
