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.

与零维纳米对象（如纳米颗粒）相反，可以在高度组织的架构中生成一维纳米材料，从而为将这些对象集成到传感器，参与者和能量收集系统等微型系统中提供了可能性。该领域为在化学，材料和工程科学的边界的合作研究联盟开设了一个承诺领域。我们正在努力研究一维纳米结构（例如碳纳米管（CNT）和金属纳米线（MNW））的集成技术。我们研究的核心目的是由垂直对齐的单个CNT或MNW的密集实体组成的3D纳米结构合奏。我们瞄准了各个组件的高纵横比结构（单个CNT和MNW> 1000）。这种方法应允许那些以横向和水平方式的微纳米结构架构成各种功能性微结构单元。由MNW和CNT组成的三维块结构的微纳米整合代表了在微工程中应得的最大研究重要性的挑战。为了达到此类目标，必须完成不同的层次结构订单（从NM到µm至mm至CM大小）的材料以及微技术知识。为了解决这个问题，我们将（i）列出以合成MNW和CNT以及（ii），以使这些纳米结构在其外表面上进行官能化和修改。为了建立整个微观结构方法，我们必须在不同的长度尺度上开发单个方法和技术解决方案。可以通过措辞多尺度整合技术来概括这项工作。作为一个典型的多尺度整合问题的模型，我们选择了一个锂离子微能蓄能器。为了应对与此相关的挑战，是在CNT和MNW结构化电子中的电化学活性材料的材料合成和沉积技术的开发以及构建和连接技术（包装），允许设置电子结构以及电子结构的最终外壳，从而建立完整的构建，这是完全操作的Micro Nanano系统。由于电子的整体微小尺寸，完整的微型能蓄能器的最终总尺寸约为1毫米。该计划的目的是，在完整资金期结束时，将作为第一个演示者单位提供这样的微型能源蓄能器。该项目开发的多尺度整合技术的知识将为各种微型工程元素（例如传感器。
