项目摘要

In contrast to zero-dimensional nano objects like nanoparticles, one-dimensional nano materials can be generated in highly organized architectures, thus offering possibilities for integration of such objects into microsystems like sensors, actors and energy harvesting systems. This area opens up a promising field for a cooperative research alliance at the borderline of chemistry, material and engineering sciences. We are strieving to investigate integration techniques for one dimensional nano-structures like carbon nanotubes (CNT) and metal nano wires (MNW). Central purpose of our research are 3D nanostructured ensembles composed of dense entities of vertically aligned single CNT or MNW. We are aiming towards high aspect ratio structures of the individual components (single CNT and MNW > 1000). This approach should allow to embed those micro-nanostructured architectures in a lateral as well as horizontal fashion into a variety of functional micro structured units. Micro-nano integration of three dimensional block structures composed of MNW and CNTs represents a challenge deserving utmost research importance in micro engineering. To reach such goals, material as well as microtechnological knowledge comprising different hierarchical orders (from nm to µm to mm up to cm size) are necessary. To tackle this we set out (i) to synthesize MNW and CNT as well as (ii) to functionalize and modify these nanostructures on their outer surface. To establish the whole line of micro-structuring methods necessary for this we have to develop individual methods and technological solutions on different length scales. This endeavour can be summarized by phrasing the term multiscale integration technique. As a model exemplifying our multiscale integration problem we have chosen a lithium ion micro energy accumulator. To tackle the challenges connected with this is the development of material synthesis and deposition techniques of electrochemically active materials onto the CNT and MNW structured electrodes as well as the construction and connection techniques (packaging) allowing to set up the electrode structures as well as the final housing of the electrodes thus building a complete, that is fully operational micro nano system. Due to the overall micro size dimensions of the electrodes, the complete micro energy accumulator will have a final overall size of about one mm. The goal of this program is that such a micro energy accumulator will be available as a first demonstrator unit at the end of the complete funding period. The knowledge towards the multiscale integration techniques developed in this project will pave the way for a wider variety of miniaturised engineering elements e.g. sensors.

与纳米粒子等零维纳米物体相比，一维纳米材料可以在高度组织的结构中生成，从而为将此类物体集成到传感器、执行器和能量收集系统等微系统中提供了可能性，这一领域开辟了一个充满希望的领域。我们正在努力研究碳纳米管（CNT）和金属纳米线（MNW）等一维纳米结构的集成技术。由垂直排列的单个 CNT 或 MNW 的致密实体组成的 3D 纳米结构整体我们的目标是单个组件的高纵横比结构（单个 CNT 和 MNW > 1000）。这种方法应该允许将这些微纳米结构嵌入到横向中。以及由MNW和CNT组成的三维块结构的水平时尚到各种功能微结构单元的微纳集成是一个值得高度研究的挑战。为了实现这些目标，包括不同等级顺序（从纳米到微米到毫米到厘米尺寸）的材料和微技术知识是必要的。（ii）在其外表面上对这些纳米结构进行功能化和改性，为了建立为此所需的整套微结构方法，我们必须开发不同长度尺度的单独方法和技术解决方案。作为说明我们的多尺度集成问题的模型，为了解决与此相关的挑战，开发了电化学活性材料在 CNT 和 MNW 结构上的沉积技术。电极以及构造和连接技术（封装），允许设置电极结构以及电极的最终外壳，从而构建一个完整的、完全可操作的微纳米系统，由于整体的微米尺寸。电极，完整的微型蓄能器的最终整体尺寸约为一毫米，该计划的目标是在整个资助期结束时，这种微型蓄能器将作为第一个演示单元提供。该项目开发的多尺度集成技术将为更广泛的小型化工程元件（例如传感器）铺平道路。
