SFB 986: Tailor-Made Multi-Scale Materials Systems - M3

合作研究中心986（SFB 986）的长期目标是开发基于功能化构建块的多尺度材料系统，这些系统无法用传统技术实现。纳米级基本功能单元，例如有机官能化纳米颗粒、金属纳米支柱、核-壳颗粒或层对，形成第一尺度水平。它们被布置在第一层次级别上，该第一层次级别表示第二标度级别。由此产生的总量，然后系统地安排在更高的层次或规模水平。这些新的材料系统将带来更好的机械、电学或光子性能，甚至允许全新的性能特征。SFB 986实现了来自材料科学、化学、物理、工艺工程和机械工程的研究团队的合作，目的是精确地调整结构特性，以满足相应材料系统的所需性能特征：·基本功能单元被安排到上层结构中，这种方法将在几个连续的离散尺度级别上扩展。在不同尺度水平上的构件之间引入了连接阶段，这也可以实现额外的功能。项目区域A旨在通过结合自下而上和自上而下的过程，优先考虑突出的机械性能，实现多尺度分层材料系统。项目领域B涉及纳米结构多相材料系统的自上而下的过程中产生的，连接强度和功能跨越几个离散的规模水平。项目领域C专注于适应性和可调的多尺度光子材料系统。在这里，自下而上和自上而下的过程都被用来开发具有定制的光学吸收，发射，反射和电荷载流子发射特性的多尺度材料系统。

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.
