| Abstract Scope |
Gas leaks remain one of the most common and costly defects within commercial refrigerant systems. Although ammonia is widely used as a refrigerant due to its diminished environmental impact over CFCs and other ozone-depleting gases, it remains toxic and flammable in high concentrations. Therefore, early leak detection is crucial. In our work, conducting polymer sensors are fabricated via inkjet printing of aqueous polyaniline (PANI) dispersions onto a polymer substrate. These flexible, low-cost devices allow for the chemical sensing of ammonia gas and address the safety, economic, and environmental issues associated with current and emerging refrigerants. The scalability of our synthesis combined with the sensitivity of PANI to ammonia make this conducting polymer an ideal candidate for commercial gas sensing applications. |
