The goal of the project is the investigation, characterization and fabrication of functional materials with extreme low densities but macroscopic expansion. The fundamental mechanical limits of ultra-lightweight materials should be explored and understood and how functional properties like electrical conductivity and light adsorption can be maintained despite the low weight. This includes free standing 3 dimensional structures as well as layers, films and thin films which are bound on a substrate. Therefore a detailed synthesis-structure- property model should be developed which enables a control of syntheses path and properties on the basis of a fundamental understanding.The synthesis concept of the preliminary experiments with Aerographite should be utilized as starting point. The sacrificial template synthesis allows a large degree of freedom in both, the inner structure as well as the general shape of the material, which enables an understanding of the resulting properties on the base of the structure variations.

该项目的目标是研究，表征和制造具有极低密度但宏观膨胀的功能材料。应该探索和理解超轻材料的基本机械极限，以及如何在重量轻的情况下保持导电性和光吸收等功能特性。这包括独立的三维结构以及结合在基底上的层、膜和薄膜。因此，应开发一个详细的合成-结构-性能模型，该模型能够在基本理解的基础上控制合成路径和性能。牺牲模板合成允许在材料的内部结构以及一般形状两者中具有大的自由度，这使得能够基于结构变化来理解所得性质。
