This Strategic Partnership project will address Canada's urgent need for developing a scalable process for the synthesis and deposition of next-generation nanoparticles (NPs) required for Advanced & Additive Manufacturing. Our unique methodology will develop a continuous reactor approach harnessing the power of supercritical fluids towards the mass production and purification of high performance 1-D metal oxide NPs in a simple flexible process. A continuous computerized reactor with online Raman & FTIR will be developed that works with a variety of metal alkoxide monomers (Ti, Zr, V, Zi) and their dopants (Bi, In, Cu) to produce high aspect ratio, high surface area, porous nanowires. Using the world leading facilities at the Canadian Light Source, we will examine the detailed mechanism of how metals are integrated into the molecular framework to control the nanoassembly and purification processes. Their integration into polymer laminates will be explored at a commercial lamination facility with ACTI, who are an ISO 9001 coating and lamination manufacturer. Our focus for these laminates will be to develop removable surfaces to combat biofouling by preventing organism attachment using a safe photocatalytic approach using our produced 1D metal oxides and their graphene assemblies. These functional antimicrobial surfaces will be applied to plasma treated two-sided tape, which can be as easily removed as Post-it notes for easy replacement and low cost installation. The mechanism of microbe attachment and removal from the surfaces and how light controls the 1D nanowires will be examined. The experimental results will be integrated into a detailed process model to control nanoparticle/laminate viscosity, thickness of layers and layer composition for demonstration trials of this technology. This proposal will provide a new way to mass produce high performance 1D nanowires and tubes suitable for Canadian industry in the emerging Additive Manufacturing area, while providing our supporting companies the ability to produce and utilize these next generation materials into high performance laminates and coatings.**************************

该战略合作伙伴关系项目将涉及加拿大迫切需要开发可扩展过程，以综合和沉积高级和添加剂制造所需的下一代纳米颗粒（NPS）。我们独特的方法将开发一种连续的反应器方法，以在简单的柔性过程中利用超临界流体对高性能1-D金属氧化物NP的质量产生和纯化。 将开发一个带有在线拉曼和FTIR的连续计算机反应堆，可与各种金属烷氧化物单体（Ti，Zr，V，Zi）及其掺杂剂（BI，IN，CU）一起使用，以产生高纵横比，高表面积，多孔纳米线。使用加拿大光源的世界领先设施，我们将研究金属如何整合到分子框架中以控制纳米隔离和纯化过程的详细机制。它们将其整合到聚合物层压板中，将在ACTI的商业层压设施中进行探索，ACTI是ISO 9001涂层和层压制造商。我们对这些层压材料的重点是开发可移动的表面，通过使用我们生产的1D金属氧化物及其石墨烯组件的安全光催化方法来防止生物固定来对抗生物污染。这些功能性抗菌表面将应用于经过血浆处理的双面胶带，可以轻松地将其与邮政注释一样容易删除，以方便更换和低成本安装。将检查微生物附着的机理和从表面上去除的机理以及光控制1D纳米线的方法。实验结果将集成到一个详细的过程模型中，以控制纳米颗粒/层压板粘度，层厚度和层组成，以进行该技术的示范试验。该提案将提供一种新的方式，以大规模生产适合新兴加法生产区加拿大工业的高性能1D纳米线和试管，同时为我们的支持公司提供能够生产和利用这些下一代材料的高性能层压和涂料。
