Hybrid materials based on nanoporous metal–hierarchy, mechanics and function (B02)

子项目B2的研究目标反映了项目区域B的上级课题：将制备具有纳米级孔隙的固体，其微观结构具有不同长度尺度的分层组织。它们的机械和功能行为将由每个层次上的系统结构控制。合金腐蚀将有助于从纳米孔金中制备具有2或3个层次和宏观样品几何形状的金属网络材料。它们的力学行为将通过实验在宏观尺度上进行研究，并将以标度定律的形式进行描述。为了展示更多面向应用的纳米多孔金属，B2还将制备纳米多孔Cu-Ni，并着眼于开发宏观驱动装置。

The research objectives of subproject B2 reflect the superordinate topics of Project Area B: Solids with nanoscale pores and with a hierarchical organization of their microstructure featuring several distinct length scales will b prepared. Their mechanical and functional behavior will be controlled by systematic structuring on each hierarchy level. Alloy corrosion will serve to prepare metallic network materials from nanoporous gold with 2 or 3 hierarchy levels and with macroscopic sample geometry. Their mechanical behavior will be investigated by experiments on the macro scale, and it will be described in the form of scaling laws. For demonstrating more application-oriented nanoporous metal, B2 will also prepare nanoporous Cu-Ni with an eye on developing a macroscopic actuation device.
