3D printed ammonia sensors from vapochromic coordination polymers suspended in Solgel

Previous work creating ammonia sensors using vapochromic coordination polymers involved either deposition via thin films or via immobilization in post arrays. This project will continue to explore new and novel deposition methods for vapochromic coordination polymers via the use of 3D printers using suspension polymers such as Sol-gel and other 3D-printable polymers. The anticipation of using 3D printers to do the deposition is that more complex geometries can be made that may aid in the creation of a more sensitive and responsive sensor compared to the previous work in thin films and other immobilization techniques. The expected outcome of this work is to show that chemical sensors fabricated by this method will have similar or better response to previously explored methods. In addition it is expected to show that this method may be more suitable in creating a low-cost, high-yield fabrication method for chemical sensors.
