项目摘要

Carbon nanotubes (CNTs) have been pivotal in generating industrial interest in nanotechnology. Their success can be quantified by the production volume of CNTs, which is growing exponentially, and is currently estimated at 5000 ton/yr. In part, this success can be attributed to the physical properties of CNTs, some of which are unlike any other engineering material (e.g. Youngs Modulus of 1 TPa, a tensile strength of 100 GPa, thermal conductivities up to 3500 Wm-1K-1). Importantly, the above off-the-chart properties only apply to high quality individual nanotubes whereas most commercial applications require tens to millions of carbon nanoparticles to be assembled into one device. Unfortunately, the mechanical and electronic properties of merit typically drop by at least an order of magnitude in comparison to the constituent nanoparticles once integrated into an assembly. It is therefore critical to develop new manufacturing processes which enable enhanced assembly of CNTs and their integration in devices. Additionally, many applications require CNTs to be interfaced with electrodes for electrical connections, as well as with liquids for sensing, microfluidic and biomedical applications, which typically require various additional advanced manufacturing processes that have several complexities and limitations.In this EPSRC Adventurous Manufacturing grant, we aim to develop innovative manufacturing techniques capable of creating structured assemblies of carbon nanoparticles with both integrated electrodes and microchannels. This requires the consolidation of manufacturing techniques that has never been attempted previously. It will allow control of structures over multiples length scales: - At the nanoscale (<500 nm), we will use chemical vapour deposition (CVD) to synthesise large arrays of aligned CNTs and self-assembly to control their organisation.- At the microscale (50 um - 500 nm), we will use multiple step lithography to define read-out electrodes and define where CNTs are synthesised.- At the largest scale (1 mm - 50 um), we will use laser processing (short and ultrashort pulses) to define microchannels and the overall chip geometry. While each of the above manufacturing techniques are well established, bringing these methods together enables the manufacturing of radically new devices. Maintaining compatibilities and alignments between different processes will create new research challenges which will be addressed in this project. Ultimately, this new set of manufacturing techniques form a platform technology that can be used to solve a multitude of engineering problems. We envision the outputs of this proposal to find applications in chemical sensors, biomedical applications, microfluidics and actuators As a demonstrator, this project will develop CNT based thrusters for space propulsion applications.

碳纳米管（CNT）在产生纳米技术的工业兴趣方面至关重要。他们的成功可以通过CNT的生产量进行量化，CNT的生产量呈指数增长，目前估计为5000吨/年。在某种程度上，这种成功可以归因于CNT的物理特性，其中一些与任何其他工程材料不同（例如，1 TPA的Youngs模量，100 GPA的抗拉机强度为100 GPA，导热率为3500 WM-1K-1）。重要的是，上述局外特性仅适用于高质量的单个纳米管，而大多数商业应用都需要将数千至数百万的碳纳米颗粒组装到一个设备中。不幸的是，与组成纳米颗粒相比，优点的机械和电子特性通常至少下降一个数量级。因此，开发新的制造过程至关重要，从而使CNT的增强组装及其在设备中的集成。此外，许多应用都需要与电气连接的电极交织在一起，以及用于感应，微流体和生物医学应用的液体，这些应用通常需要各种其他高级制造过程，这些过程具有多种复杂性和限制。微通道。这就需要以前从未尝试过的制造技术的整合。它将允许控制倍数长度尺度的结构： - 在纳米级（<500 nm），我们将使用化学蒸气沉积（CVD）合成大量的对齐的CNT和自组件来控制它们的器官。规模最大（1 mm -50 UM），我们将使用激光处理（短和超短脉冲）来定义微通道和整体芯片几何形状。尽管上述每种制造技术都已确定，但将这些方法融合在一起，可以制造出根本新的设备。保持不同流程之间的兼容性和一致性将带来新的研究挑战，这些挑战将在本项目中解决。最终，这种新的制造技术构成了一种平台技术，可用于解决多种工程问题。我们设想该提案的输出，以在化学传感器，生物医学应用，微流体和执行器作为演示器中找到应用，该项目将开发用于太空推进应用的基于CNT的推进器。
