This proposal outlines a research program on the scalable nanomanufacturing of 2D materials and their functional integration into systems and devices that benefit from nano-size scaling. 2D nanomaterials capture the essence of atomic-size effects, and can benefit a diverse range of applications from mechanical properties, electrical and thermal conductivities, high surface areas and unique quantum-mechanical effects. However, their full potential in everyday life is limited by the current methods of fabrication which compromise either quality or quantity. The proposed program seeks to address fundamental scientific and applied issues in production scaling of top-down processed 2D material systems by researching the recently conceived compressible flow exfoliation (CFE), which is a continuous and high-throughput method for mechanically exfoliating 2D layered materials using supersonic flows. The proposed research program seeks to elucidate the fundamental processing-structure-property relations regarding CFE that are necessary for any bench-to-floor transition. The approach will consist of (1) using theory and numerical tools, coupled with experimental observations to establish the exfoliation mechanism, (2) optimize the processing and post-processing conditions for fully continuous operations, (3) demonstrate feasible applications of CFE processed 2D nanomaterials in nano-enabled systems such as flexible electronics, thermal management and synthetic-nacre systems. Through this work, which will involve a total of 10 HQP (4 MS, 2 PhD and 4 UG), several existing knowledge gaps surrounding the (i) theory of 2D material fragmentation, (ii) effect of treatment time on 2D material quality, and (iii) continuous, rapid and environmentally friendly processing of 2D materials will be addressed. The promise of graphene and other 2D nanomaterials has not delivered thus far, because of a major disconnect between what's happening in the lab vs. the factory floor. A recent study (Kauling et al. 2018 in Advanced Materials) examined "graphene" from 60 suppliers and found that most were just expensive milled graphite and that on average only 10% of the product was 10 atomic layers or less. These purely commercial, smoke-and-mirror ventures are detracting from the fundamental R&D efforts that are still needed in scalable nanomanufacturing of 2D materials resulting in calls for developing standards for product qualification from organizations like International Organization of Standards (ISO) and the UK's National Physical Laboratory. The proposed research program on scalable nanomanufacturing of 2D materials and their integration into nano-enabled systems will rely on established as well as emerging concepts from 2D materials science, compressible gas dynamics, colloid surface science and composites design principles. It will benefit the Canadian natural resources and manufacturing sectors through the ensuing R&D and the skills and experience training of HQP.

该提案概述了一项研究计划，涉及2D材料的可扩展纳米制造及其功能整合到受益于纳米尺寸缩放的系统和设备中。 2D纳米材料捕获了原子大小效应的本质，并且可以使各种应用从机械性能，电导率和热导电性，高表面积和独特的量子力学效应中受益。但是，它们在日常生活中的全部潜力受到损害质量或数量的当前制造方法的限制。拟议的计划旨在通过研究最近构想的可压缩流质（CFE）来解决自上而下处理的2D材料系统生产规模的基本科学和应用问题，这是一种使用机械去角质的2D层次材料的连续且高通量的方法超音速流。 拟议的研究计划旨在阐明与CFE有关CFE的基本处理结构关系，这对于任何台阶到地板过渡都是必需的。该方法将包括（1）使用理论和数值工具，再加上实验观察以建立去角质机制，（2）优化用于完全连续操作的处理和后处理条件，（3）证明了CFE处理的2d的可行应用支持纳米材料的纳米材料，例如柔性电子，热管理和合成 - 核系统。通过这项工作，该工作将涉及10 hqp（4 ms，2 phd和4 ug），围绕（i）2D材料碎片理论的几个现有知识差距，（ii）治疗时间对2D材料质量的影响， （iii）将解决2D材料的连续，快速且环保的处理。 迄今为止，石墨烯和其他2D纳米材料的承诺尚未交付，因为实验室与工厂地板之间发生的事情之间存在重大脱节。最近的一项研究（Kauling等人，2018年在高级材料中）检查了60个供应商的“石墨烯”，发现大多数是昂贵的石墨，平均只有10％的产品为10个原子层或更少。这些纯粹的商业，烟雾企业正在损害基本的研发工作，这些研发工作仍需要在2D材料的可伸缩纳米制造中需要，从而呼吁为国际标准（ISO）和英国国家国家国家组织（ISO）等组织制定标准的呼吁实验室。拟议的关于2D材料可扩展的纳米制造的研究计划及其在纳米支持系统中的集成将依赖于已建立的以及来自2D材料科学，可压缩气体动力学，胶体表面科学和复合材料设计原理的既定概念。它将通过随之而来的研发以及HQP的技能和经验培训来使加拿大自然资源和制造业受益。
