项目摘要

Access to nanomaterial building blocks with precisely controlled size, shape and composition has created a fertile opportunity space for emerging nanotechnologies. Prototype nanomaterial-enabled technologies spanning sensors, membranes, catalysis, data storage, electronics, displays, photovoltaics, energy storage, and thermoelectrics have generated high expectations for their commercialization. However, there is growing recognition that sustained progress towards the acclaimed promise of nanomaterial-enabled technologies depends critically on solving outstanding fabrication challenges; in particular the need to bridge the length-scale gap between millimeter scale devices and nanometer scale components. This research will develop spearheading nanomanufacturing capabilities to fabricate materials and devices with precisely programmed structure, composition, and function across six orders of magnitude in length scale. The research is driven by the vision that combined control over individual nanostructures (at atomistic length scales), programmable molecular assembly of micrometer superstructures and advanced manufacturing methods (spanning micrometer to meter) presents exciting prospects to manufacture new classes of materials and devices. Beyond the scientific and technological impact of advanced nanomanufacturing capabilities, the educational objectives of this project will focus research opportunities for undergraduates and minorities by developing interactive 3D printing learning modules. The confluence of advances in directed assembly of nanomaterials and additive manufacturing technologies create powerful prospects to address critical challenges in scalable nanofabrication. On the one hand, technological applications of self-assembled nanostructures (e.g., nanoparticle superlattices) are limited by the lack of scalable fabrication methods. On the other hand, currently available 3D printing technologies are limited by speed, spatial resolution and material diversity. This project will explore synergies at the intersection of these two fields. The research team embraces the challenge of bridging this length scale gap as an opportunity to develop novel nanomanufacturing techniques that synergistically combine recent advances in molecular-level assembly and additive 3D printing. This project will explore the concept of continuous additive nanomanufacturing at Fluid Interfaces (CANFI). New knowledge from the project will establish the scientific and engineering foundation for advanced hierarchical nanomanufacturing techniques that span 6 orders of magnitude in length scale. Beyond the specific model systems at the focus of the work, the knowledge generated from this work is expected to have significant multiplying effects and will likely spur additional nanomanufacturing advances in related fields.

访问具有精确控制尺寸，形状和组成的纳米材料构建块为新兴纳米技术创造了肥沃的机会空间。原型纳米材料的技术涵盖传感器，膜，催化，数据存储，电子设备，显示，光伏，能量存储和热电话对其商业化产生了很高的期望。但是，人们越来越认识到，朝着支持纳米材料的技术的著名承诺的持续进展取决于解决杰出的制造挑战。特别是需要弥合毫米尺度设备和纳米尺度组件之间的长度尺度差距。这项研究将开发带头的纳米制造能力，以制造具有精确编程的结构，组成和功能的材料和设备，跨长度尺度的六个数量级。这项研究是由对单个纳米结构（原子长度尺度），可编程分子组装的视野驱动的。除了先进的纳米制造能力的科学和技术影响外，该项目的教育目标还将通过开发互动3D打印学习模块来重点研究本科和少数民族的研究机会。纳米材料和添加剂制造技术的指示组装进展的汇合创造了强大的前景，以应对可扩展纳米型的关键挑战。一方面，自组装纳米结构（例如纳米颗粒超晶格）的技术应用受到缺乏可扩展制造方法的限制。另一方面，当前可用的3D打印技术受速度，空间分辨率和物质多样性的限制。该项目将在这两个领域的交集中探索协同作用。研究团队面临着弥合这一长度规模差距的挑战，是开发新型的纳米制造技术的机会，该技术协同结合了分子级组装和添加剂3D打印的最新进展。该项目将探讨流体接口（CANFI）连续添加纳米制造的概念。该项目的新知识将建立高级分层纳米制造技术的科学和工程基金会，该技术的长度范围为6个数量级。除了工作重点的特定模型系统之外，这项工作产生的知识预计将产生重大的乘法效果，并可能刺激相关领域的其他纳米制造进展。
