Silver nanowires (SNW) are among the most promising nanomaterials for modifying electrical properties of advanced multicomponent systems due to their large length to diameter ratio, nanometric diameter, and exceptional electrical conductivity. As the result they have become key functional component in novel applications including flexible transparent electrodes for displays or solar panels, sensors, thermal coatings, catalysts, and conductive inks and adhesives. Several physical and chemical methods have been developed for production of nanowires, among which the polyol reactions have been proven efficient for making SNW with a range of lengths and diameters at laboratory-scale. The remaining challenge is scaling-up the reaction and purification procedure for cost-effective, high-yield production of nanowires with controlled properties.Here we are proposing a collaborative R&D project on pilot scale production of various grades of silver nanowires. The research involves systematic study of the major factors influencing the synthesis and purification of the nanowires via extensive analysis of the reaction pathway and the outcome of an array of experiment. The production capacity will be expanded in multiple steps alongside thorough analysis of the product. Required modifications will be applied to ensure the desired quality is maintained at each step. The results will be used to implement an optimized, economically viable pilot-scale process for high-yield, controlled production of SNW. The feasibility of automating the established process will then be examined to improve the product consistency. Also, a hypothesis will be developed to elucidate the reaction mechanism and provide guidelines for further increase in production scale. Successful completion of this research is the first step towards commercial production of SNW and SNW-based advanced materials. At least two interns will be trained, and one full-time position will be created. We expect to publish and present a portion of the results of this study. We will also consider the possibility of patenting the SNW production process.

银纳米线（SNW）是最有前途的纳米材料之一，用于修饰高级多组分系统的电气性能，因为它们的直径较高，直径较大，纳米直径和出色的电导率。结果，它们已成为新型应用中的关键功能组件，包括用于显示或太阳能电池板，传感器，热涂层，催化剂以及导电墨水和粘合剂的柔性透明电极。已经开发了几种物理和化学方法来生产纳米线，其中已证明多元元反应在实验室尺度上具有一系列长度和直径的SNW有效。剩下的挑战是扩大具有受控特性的纳米线的成本效益，高收益产生的反应和纯化程序。在这里，我们提出了一个协作性的R＆D项目，以实行各种级别的银纳米线生产。该研究涉及对影响纳米线的合成和纯化的主要因素的系统研究，这是通过对反应途径的广泛分析和一系列实验结果的广泛分析。生产能力将在多个步骤中扩展，并对产品进行彻底的分析。将应用所需的修改以确保在每个步骤中保持所需的质量。结果将用于实施优化的，经济上可行的试验规模的过程，用于高产，受控的SNW生产。然后，将检查自动化建立过程的可行性，以提高产品一致性。同样，将开发一个假设来阐明反应机制，并为进一步提高生产量表提供指南。这项研究的成功完成是迈向基于SNW和SNW的高级材料的商业生产的第一步。至少将培训两个实习生，并将创建一个全职职位。我们希望发布并介绍本研究结果的一部分。我们还将考虑为SNW生产过程申请专利的可能性。
