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

986合作研究中心（SFB 986）的长期目标是开发基于功能化构建模块的多尺度材料系统，这是传统技术无法实现的。纳米级的基本功能单元，如有机功能化纳米粒子、金属纳米柱、核壳粒子或层对，构成了第一级尺度。它们被安排在第一个层次上，这代表了第二个尺度层次。由此产生的聚合体然后被系统地排列在更高的层次或规模水平上。这些新颖的材料系统将带来更好的机械、电气或光子特性，甚至可以实现全新的特性。SFB 986已经实施了来自材料科学，化学，物理，工艺工程和机械工程的研究团队的合作，其目的是精确地调整结构特性，以达到各自材料系统所需的性能特征：•基本功能单元被安排到上层结构中，这种方法将扩展到几个连续的离散尺度水平。•连接阶段，也可以实现额外的功能，在不同规模的构建模块之间引入。项目区域A旨在通过结合自下而上和自上而下的工艺，优先考虑突出的机械性能，建立多尺度分层材料系统。项目领域B涉及在自上而下的过程中生产的纳米结构多相材料系统，将强度和功能连接在几个离散的尺度水平上。项目领域C侧重于适应性和可调谐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光学吸收、发射、反射和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.
