Green roll-to-roll (R2R) manufacturing can enable eco-friendly and economical fabrication of modern flexible electronics. With rapidly growing markets for flexible electronic displays, solar cells, electronic skin and the internet of things (IoT), key challenges for massive scale manufacturing need to be addressed, including cost, performance, environmental friendliness of fabrication processes and reusability of materials and substrates. Achieving highly conductive, reliable and low-cost electric interconnects and related electronic devices is critical for the development of industrial scale R2R production of flexible electronics. However, solutions for stable, highly conductive materials often rely on expensive source materials (e.g., silver) and produce toxic waste arising from post processing and etching. Considering the exponential growth in electronic waste, it is imperative to look for solutions that are more friendly to environment and still meet the requirements of the growing electronics industry. This project brings a strong team of researchers and laboratories at UBC in collaboration with a world-leader in flexible electronics, TF Massif, located in Burnaby, BC, to develop solutions that address these critical challenges. The project will focus on development of complementary solutions for direct print nano-inks, vacuum deposition techniques, post processing and ablation materials that enable use of multi-layered, highly conductive and patternable interconnects and electronic devices on a variety of flexible substrates including polyethylene terephthalate (PET), polyimide (PI), clear PI and other flexible substrates that are bio-sourced and biodegradable. The project will investigate the processes and associated in-depth material properties that can provide high conductivity, bonding to flexible substrates and stability in frequent mechanical bending, stretching and exposure to environmental changes and chemicals. By developing advanced processes and nano-inks that are amenable to massive area and low-cost flexible electronics, this project opens significant opportunity for TF Massif and other Canadian industry leaders to develop a globally competitive advantage and define future markets in green R2R manufacturing and create jobs for Canadians.

绿色卷对卷 (R2R) 制造可以实现现代柔性电子产品的环保且经济的制造。随着柔性电子显示器、太阳能电池、电子皮肤和物联网 (IoT) 市场的快速增长，需要解决大规模制造的关键挑战，包括成本、性能、制造工艺的环保性以及材料和基板的可重复使用性。实现高导电性、可靠且低成本的电气互连和相关电子器件对于柔性电子产品工业规模 R2R 生产的发展至关重要。然而，稳定、高导电性材料的解决方案通常依赖于昂贵的原材料（例如银），并在后处理和蚀刻中产生有毒废物。考虑到电子废物呈指数级增长，寻找对环境更加友好且仍能满足不断增长的电子行业要求的解决方案势在必行。该项目汇集了 UBC 强大的研究人员和实验室团队，与位于不列颠哥伦比亚省伯纳比的柔性电子领域的世界领先者 TF Massif 合作，开发解决这些关键挑战的解决方案。该项目将重点开发直接印刷纳米油墨、真空沉积技术、后处理和烧蚀材料的补充解决方案，从而能够在包括聚对苯二甲酸乙二醇酯在内的各种柔性基材上使用多层、高导电性和可图案化的互连件和电子器件(PET)、聚酰亚胺 (PI)、透明 PI 和其他生物来源且可生物降解的柔性基材。该项目将研究工艺和相关的深入材料特性，这些特性可以提供高导电性、与柔性基材的粘合以及在频繁机械弯曲、拉伸和暴露于环境变化和化学品中的稳定性。通过开发适用于大面积和低成本柔性电子产品的先进工艺和纳米油墨，该项目为 TF Massif 和其他加拿大行业领导者提供了重要机会，以发展全球竞争优势，定义绿色 R2R 制造的未来市场，并创造加拿大人的工作。
