The long-term objective of the Collaborative Research Center 986 (SFB 986) is to develop, based on functionalized building blocks, multiscale materials systems which cannot be realized with conventional techniques. Nanoscale elementary functional units, such as organically functionalized nanoparticles, metal nanostruts, core-shell particles or layer pairs, form the first scale level. They are arranged on a first hierarchy level, which represents the second scale level. The resulting aggregates then are systematically arranged on higher hierarchy or scale levels. These novel material systems will lead to qualitatively better mechanical, electrical or photonic properties or even allow for completely new property profiles.SFB 986 has implemented a cooperation of research teams from materials science, chemistry, physics, process engineering and mechanical engineering, with the aim of adjusting the structure characteristics precisely to the desired property profile of the respective materials system:• Elementary functional units are arranged into superstructures, and this approach will be extended over several consecutive discrete scale levels.• Connecting phases, which also may enable additional functions, are introduced between the building blocks on different scale levels.Project area A aims at multiscale hierarchical materials systems by combining bottom-up and top-down processes, prioritizing on outstanding mechanical properties. Project area B deals with nanostructured multi-phase materials systems produced in a top-down process, connecting strength and function across several discrete scale levels. Project area C focuses on adaptable and tunable multiscale photonic materials systems. Here, both bottom-up and top-down processes are used to develop multiscale materials systems with tailored optical absorption, emission, reflection and charge-carrier emission properties.
