Mass production of metal oxide nanoparticles and their integration into polymer coatings

该战略合作项目将解决加拿大迫切需要开发一种可扩展的工艺，用于合成和沉积先进和增材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反应器方法，利用超临界流体的力量，在简单灵活的过程中大规模生产和纯化高性能一维金属氧化物NPs。将开发一种具有在线拉曼和红外光谱的连续计算机反应器，该反应器与各种金属醇氧单体（Ti, Zr， V, Zi）及其掺杂剂（Bi, In, Cu）一起工作，以生产高长径比，高表面积，多孔纳米线。利用加拿大光源的世界领先设备，我们将研究金属如何整合到分子框架中以控制纳米组装和纯化过程的详细机制。他们整合到聚合物层压板将探索在一个商业层压板设施与actii，谁是一个ISO 9001涂层和层压板制造商。我们对这些层压板的重点是开发可移动表面，通过使用我们生产的1D金属氧化物及其石墨烯组件，使用安全的光催化方法防止生物附着，从而对抗生物污染。这些功能性抗菌表面将应用于等离子处理的双面胶带，它可以像便利贴一样容易去除，易于更换和低成本安装。将研究微生物附着和从表面去除的机制以及光如何控制1D纳米线。实验结果将整合到一个详细的过程模型中，以控制纳米颗粒/层压板的粘度、层厚和层组成，以进行该技术的示范试验。该提案将为加拿大工业在新兴的增材制造领域大规模生产高性能1D纳米线和纳米管提供一种新方法，同时为我们的支持公司提供生产和利用这些下一代材料制成高性能层压板和涂层的能力。

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.
