Nickel is a vital element with wide-ranging applications in both industry and consumer products, from stainless steel and magnets to rechargeable batteries. Canada has identified nickel as one of its critical minerals, recognizing its potential to drive economic growth. Vale Base Metals, headquartered in Ontario, Canada, is a leading global producer of nickel. The production of nickel involves the synthesis and use of nickel carbonyl (Ni(CO)4), a highly toxic compound with a low occupational exposure limit of 50 ppb, posing substantial workplace hazards. Ensuring Ni(CO)4 levels remain below this limit in the nickel manufacturing environment is paramount. However, existing Ni(CO)4 sensors on the market are cumbersome, expensive, and not ideal for Vale Base Metals' needs. The company urgently requires lightweight, portable/wearable, and cost-effective Ni(CO)4 sensors to enhance workplace safety.To address this critical need, the University of Waterloo and Vale Base Metals have joined forces to develop innovative, portable/wearable, and affordable Ni(CO)4 sensors. The research focuses on creating novel polymer semiconductors that strongly interact with Ni(CO)4, resulting in significant changes in the polymer's electrical and optical properties. These polymers will serve as the active components in three types of lightweight optoelectronic devices: chemiresistors, organic field-effect transistors, and fluorimeters. These devices will be manufactured using cost-effective methods such as roll-to-roll printing on flexible plastic substrates, making them ideal for portable and wearable applications.This technology will significantly enhance workplace safety, protecting the health and lives of employees while promoting nickel production. It will bring substantial benefits to Vale Base Metals and contribute to Canada's economic growth. Moreover, the technology's adaptability allows for easy integration into fields like wearable electronics and the Internet of Things. Additionally, the project will provide training for highly qualified personnel with expertise spanning multiple disciplines.
