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

该战略伙伴关系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，以简单灵活的工艺大规模生产和纯化高性能一维金属氧化物纳米颗粒。 将开发具有在线拉曼和FTIR的连续计算机化反应器，其与各种金属醇盐单体（Ti、Zr、V、Zi）及其掺杂剂（Bi、In、Cu）一起工作以产生高纵横比、高表面积、多孔纳米线。利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组装和纯化过程的详细机制。将在与ACTI的商业层压设施中探索它们与聚合物层压板的集成，ACTI是ISO 9001涂层和层压制造商。我们对这些层压材料的重点将是开发可移动表面，通过使用我们生产的1D金属氧化物及其石墨烯组件的安全光催化方法防止生物附着来对抗生物污垢。这些功能性抗菌表面将应用于经等离子体处理的双面胶带，该双面胶带可以像便利贴一样轻松移除，便于更换和低成本安装。微生物附着和从表面去除的机制以及光如何控制一维纳米线将被检查。实验结果将被整合到一个详细的工艺模型中，以控制纳米颗粒/层压材料的粘度、层的厚度和层的组成，用于该技术的示范试验。该提案将提供一种新的方式来大规模生产适用于加拿大新兴增材制造领域的高性能1D纳米线和纳米管，同时为我们的支持公司提供生产和利用这些下一代材料的能力，以实现高性能层压材料和涂层。

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.**************************
